General Grievous needs a rework

I think most people can agree that General Grievous is one of the most underwhelming dark side droids. Even Imperial Probe Droid is better. I think the reason for this is the way his kit simply doesn't synergize at all. Half of his kit has potential to break through the defensive teams that are currently the meta, such as an uncounterable basic, an aoe that inflicts healing immunity, and an ability that inflicts health down, but his leader ability seems to work against all of that by trying to weaken teams that are heavily offensive by building around crits. He doesn't even do that well because most teams that are going to build around crits are STILL going to have somewhat of a net positive gain.

Not to mention, while his tactical retreat is a unique ability, it needs something else. The max health gain is nice, but the forced taunt on a random ally can either save you or make things worse depending on if your support gets taunted or not. Perhaps a rework could choose which ally gets taunted, considering he is a commander.

A rework to his leader ability, I think, would be most effective in bringing his effectiveness up. Instead of crit down, maybe he can do counter chance down. I would actually like to see counter chance down by a substantial margin when zeta'd, since while Grievous has no problem dealing with enemies that counter, they could be damaging to the rest of his team.
