Limiting Engineer from using the full effects of his turret could be a good way to nerf him. He sometimes does feel like a defensive / support class. You can still kind of rush players with Double Time + Stun if they get in range. Not sure if it's balanced, but it is fun. I guess to put it simply, there is a bigger incentive for Engineer to camp rather than support his team.
Scientist still has the same problems since day one, which is that Warp activates instantly. He can still be played too aggressively, and the instant Warp allows too much survivability. I personally do not like Sticky Healy Thingy either and it's higher heal rate. Steam Blaster has great close range damage, and it doesn't help that some plants do really mediocre damage in comparison, like Corn, Sunflower, and probably Nightcap and Rose.
I also think Healing is kind of annoying. It completely shuts down a lot of important effects too like 80's tags, Butter Beacon, and Fire damage. It makes playing higher ROF classes less fun, but this is mostly due to their low damage output. In my opinion, the primary damage of some classes' are too low for them to kill supports effectively, and some of them are attack classes.
@Pheesley I have to agree on your points. Healing feels too good right now and Scientists that focus on healing don't do as well on the boards as those that go aggressive. Also if you play a heavily healing focused scientist, you have to shoot or use healing hose. This is a huge change from GW1 where you had to rely on placing your heal station down and GW2 where you used the beam that was much like the Sunflower heal beam or the station, supplemented if you liked with the mega-heal ball. All of these allowed you to shoot while healing so even while playing an aggressive scientist, you could still heal your team. In BfN you have to choose to focus on healing or shooting. The Heal Thingy helps with this, but I'm not surprised at all that many scientists just go aggressive and ignore the healing hose altogether. The Steam Blaster merely magnifies the lure of going full on attack as a Scientist, especially with 3 instant warps.
I was playing some GW1 recently and the difference in Sunflower healing (I didn't play Scientist) between that game and here is very obvious. It took me awhile to get a cactus from almost down to full health in GW1, whereas in BfN it's very fast, even taking the lower health cacti have here than GW into account. they mentioned looking at healing before, and it really looks like they need too. I wouldn't mind other healing classes added eventually, but first they need to deal with the healing as it is now.
