I'm probably alone on this but I think Jar-Jar Binks and OOM-9 could make interesting heroes... if we have a football beating Vader, why couldn't we have the smartest B1 defeating Jedi? And Jar-Jar... he would probably be a meme character and is very hated, but again, there are already some characters ingame lot of people dislikes. I always think while its interesting and the gameplay works, even the worst characters are fun to play. So, some basic concept (if anyone is interested):
Jar-Jar: attacks with the gungan electropole - similar to Phasma's staff, but faster, different animation. Altough a melee character, but doesn't do as much damage as a lightsaber. His sprint speed and jump is similar to Bossk.
Health: 800; Health regen: 300
Abilities:
Left - Boomas; the traditional gungan electric grenades. Jar-Jar carries 3 of them at a time, that he can use similar to Leia. Boomas do less damage and have a smaller blast radius, but have increased damage agains vehicles and can stun heroes for a bit.
Right - Fool's luck; Jar-Jar is a bit of an idiot, but he's lucky for sure. While the luck is active, Jar-Jar recieves a health buff, an extra dodge, increased sprint speed and is hidden from enemy radars.
Middle - Confuse; Jar Jar's presence can be really annoying. I imagine Confuse working as the opposite of Finn's big deal - sintead of buffing your team, debuffs the enemy team. Their radars are scrabled if they're in Jar Jar's ability radius, their weapon gains more recoil, making aiming harder, and their abilities have a slower recharge rate.
OOM-9: carries a modified E-5 blaster rifle that has infrared vision when aimed with.
Health: 600; Health regen: 450
Abilities:
Left - Commander; During this ability, OOM-9 buffs himself and his teammates in a large radius - their health slowly regenerates, their abilities instantly refresh and their weapons get overloaded. The ability lasts for 8 secs.
Right - Orbital strike; OOM-9 calls down an orbital strike from the droid command ship that damages anyone in its radius. Inside, the orbital strike works as a shock trap, knocking multiple enemies down.
Middle - Ranged more; OOM-9 switches his weapon to a powerful sniper that shoots piercing bolts with the ability to damage multiple enemies at once. Can go through blocks and shileds, but has a slow fire rate and the player has to charge it for bigger damage.
Emotes: "Open fire!" "You will not stay hidden for long" "Seize fire"
The biggest problem with this hero is its looks on clone wars maps; in the heat of the battle, it would be really hard to see the difference between OOM-9 and the other B1-s. Even though in the movies he has yellow marks, switching it to a distinctive, bright orange color could help.
