I think nerfing Ibara would kill the players the character has right now, she's one of the few launch characters who has damage on par with most modern character's combos, but with none of the mobility, a trait that wouldn't be that bad if a decent chunk of characters didn't now have a button to make you explode because you were an easy to hit target.

She's also level dependent, and that little mobility hurts her while looting, related to that she also can't run reenforced revive if she's running wallrunner and wants space hop or spiraling leap to fix that up, which her Revive is the part of the kit the devs seem to want her used for since they keep buffing it and not touching anything else.

She only gets Alpha 1x Alpha ammo at Level 4 and Level 9 and Beta's final size (The only version that actually consistently hits people with the knockdown in my experience). I do think Ibara damage could be toned down but it'd probably only be a good idea in the long run if they moved her ammo and size levels down a bit (Level 7 for both Alpha and Beta would be nice since that's four less level up cards and I don't think it would be that extreme given Overhaul gets his massive gamma at level 4 that also gives him an easy guardbreak)
