The thing is, he isn't intended to be a murder machine that's in a tier above other characters. He's not intended to be something you rush to get. He's intended to be something to do with the extra shards you've gotten over time--that's all.
He hits like a truck, having one of the highest base attacks in the game. He's slow, but that can be adressed with HK-47 or even Lobot as a leader and Poggle or Jawa Engineer as allies. He's not supposed to be a one man wrecking crew, but part of a larger team.
(I hate his Health Down debuff, though... Either needs more potency so the turn meter reduction hits more reliably, or it needs to be replaced with something else entirely. It's such a liability on defense knowing that his third attack won't do anything useful.)
