Harley is overall a great character, but these are some changes I'd like to see.
Buffs:
Her trait is worthless because of flower and picture. Reduce their recovery frames.
Improve either the hitbox or start-up of Heads Up so it's not such a shitty anti-air.
Widen the special cancel window on D2. It's ridiculously stringent, just a quality of life buff.
Nerfs:
Reduce the block stun on 2D3 a little. +10 is borderline OP.
She really doesn't need a trait imo....but if you like trait, keep the life lead in the match. Land a super and take a risk. Thats what I like
About the trait, because if you risk trait and get dynamite, that's a free 40% unblockable reset.
For aa gun shot you only use it if you know they're jumping, its actually not as terrible as you think. Otherwise neutral jump 2 usually always wins.
D2 I think is honestly useless...if you want reliable anti air, use b3 instead...its also plus on block.
Idk I really use 2d3 a lot...it helps against players who block well and I use it to open them up. But i could live with that only if
They improved the hitbox on 1. The range is wonky...and considering this is one of the fastest in the game at 4 frames, its lame it hits random at times.
Harley doesn't need a buff or nerf...her trait is crap because her rushdown is so strong that if they made trait in a way where you get dynamite with a meter burn she would be absolutely broken, because dynamite is a free 40% setup and nobody else can mb their trait. Same for silly slide. Being able to cancel silly slide to tantrum is already really strong and super. Mb B3 is your best friend with harley.
