The only selfish thing Gravion has is that 100% fill rate buff. Besides that, he can lower attack, which can stack with mitigation for ridiculously low damage, and buffs crit damage, all on SBB, combined with a crit rate buff on BB. That's not even considering the fact that he's a nuker. He may not have the same attack buffs and crit damage buffs that Hadaron has (the ultimate selfish unit in my opinion), but with a 1000% multiplier, he'd be a pretty big team player with all his buffs.
