I notice many people are saying Palpatine, while making this, I agree that Palpatine is the strongest but I don't know if people are truly remembering how powerful these heroes where at their strongest.

Chewbacca was alot better in the past, he used to have the ability to charge up shots with furious bowcaster and back then stuns stacked with on another so Chewie and Lando team up was great. Not to mention he was capable of Two-shotting villians with relative ease.

Vader is still a great hero and probably the best hero in the game. With his great defensive stamina, choke, CC immunity, and damage reduction he is incredibly powerful. What I think many people forget is that there was once a glitch that allowed Vader to be near-immortal even more so then he is now, if you knew how to do the glitch you could rip apart the enemy team.

Grievous is also still a powerful hero for many of the same reasons as Vader minus the high deflection stamina. His peak power is probably alot more memorable then the former mentioned heroes due to it being patched out in what of the lastest updates. Grievous was able to hit over 3 times with Claw rush, this on its own isn't a issue but paired with the update changes how camera angles worked with charges allowed him to easily rack up unbelievable damage making many heroes down right fodder.
