My Opinion

Anyone using them in HvV is practically a free kill imo

 Yet they can be very annoying in Galactic Assault, especially BB8. BB9E is weak and I've never seen anyone playing him ending up in the top players. His abilities are all supportive and his damage output is ridiculous for a hero. Any experienced heavy infantry player can outdamage BB9E, especially if we consider his range is only about 2 meters. He can be fun to play as some weird football-assasin, rushing in with smoke screen and picking off two-three enemy soldiers, then disappearing in the heat of the battle, but don't except getting high scores or killstreaks with it. He's a good support character in HvV when you have a good team, but can't take a Luke or an Anakin on its own (if they now what theyre doing of course) - and this is exactly right this way.

BB8 on the other hand, has one of the most powerful abilities in the game, and I still think its a shame such a disliked, uninteresting dumb character got. Cable spin can clear entire rooms, rolling charge is as good as Han's shoulder charge, and he can also weaken eneimes so they take more damage. An experienced BB8 can make a huge mess in the enemy team, is great to hold control points and stronger saber heroes can't always just chase him down in GA. I think Dice really did a good job making him playable, because I really couldn't imagine how would that be possible, but it just feels wrong. Ventress-Ashoka; Qui-Gon - Plagueis; Mace Windu - Savage Opress, even R2-D2 would have been a better choice, yet they still picked the two no one wanted to see.

And I thinik the solution would be a grapple move. Heroes on both side can perform this move if they use melee strike on a smaller target (the BB uints). They basically just pick them up and instakill them in one move... just imagine Vader or Grievous ripping off the head of BB8. The downside is the move takes about 3-4 seconds to perform, so it cannot be used in wide open areas with lots of enemy troopers.

@FearfulWarpIII have met some few people that are really good with the droids in HvH, especially as BB-9E because of the stun mechanic, but yeah, most people just wouldn't roll with them. (badum-tss)

I use BB-8 sometimes when I play with a stacked/better team because like for the blaster heroes with less overkill abilities, you'll need some team mates that care a little to cover or just stay near you.

Anyways, there are basically no better heroes for infantry modes than the droids.

Like Yoda, the small hitbox size is a great advantage for survivability and not being spotted that easily.

Also they're fast, have a fast health regeneration and, what's most ridiculous, they have a star card for increased max health regeneration.

Like wtf, Yoda doesn't have such a card, Maul doesn't, Luke and Kylo as well but the most difficult to hit targets do? That shows how well balanced the star card decks of newer heroes are while the deck of release heroes are often full of more useless cards or are outdated completely.

Also both can obliberate even large groups of infantry quite easily.

@CoffeeTonicYou should play BB-9E more. He isn't weak at all in infantry modes. I play him often and the stun ability works greatly to my advantage. Also you can dispatch even infantry groups relatively easy with his middle ability. You just need to equip the dmg increase cards. Also the fog will make it even more difficult for your opponents to find and shoot you then.

So no, BB-9E isn't really weaker than BB-8 in infantry scenarios because infantry doesn't have that much health.

With stun he's even better off against enforcers than BB-8 with his normal attacks.

Only in HvH is that significant difference present because of the insane cable dmg output of BB-8, even while pushed or pulled.  But then again, stun attacks of BB-9E.

Character development at it's finest............ 

........... cough

A decent BB-8 in GA and Supremacy can win in the indoor phases any day of the week. In HvV, a BB-9E that sticks close to good saber hero will make a LS lobby rage quit. The big issue is that they both have a very high percentage of not getting affected by Force abilities. At times, saber strikes seems to go right through them.

I know they had (i'm guessing) to come up with DS heros to tie-in with TROS but this was a poor choice and not well thought out. We got another DS character with stun ability, AND that can heal and obstruct view, and a character that had 30 seconds of screen time in the previous film. You could have put in Hux or Pryde, and model him after Krennic, and Zorii Bliss, who you could've put a jetpack on her and you would've had a proper counter to Boba.     

They are unnecessary content that was a complete waste of dev time. Nobody asked for them and we could have gotten more important content like maps, skins, or blasters. 

They should of spent there time on maps at least for all  modes

Arcade should have had a large scale mode 

No service no servers no internet and no good offline content as in a large  single or multiplay game mode eg Ga or supremacy 

Then there isn't  much of a game 

I'm sure heaps of you would love playing with a friend or family member offline in a large Battle in different era's and map's 

If they had done this

Sure add the bowling balls😉

I feel like the only one who likes them. They are pretty fun and unique. BB-8 is a strange glass cannon. BB-9E, on the other hand, is capable of infuriating enemy teams, and is a good support unit. 
I think that these heroes, with the way they are made, was probably the best we could have gotten from the ending support of this game. Think about it from a developer’s viewpoint. Both of the BBs don’t have voices, so you don’t need to hire multiple voice actors for different languages. They are similar, with models that are very close. They tie in to a new movie coming out. They are pretty iconic, which is good for advertising. Also, they bring new heroes to the most ignored trilogy in the game. 
I welcome any new content to the game. Could we have gotten better stuff? Of course. But they make the Sequel trilogy really fun to play. So I don’t really mind them being included at all.
