You're the best Arrow right now and I trust your judgementt but I thought Arrow was nerfed before? I don't think I noticed any buffs for him either, maybe I'm not paying attention.
I'd also like to know what MUs you think he wins that others don't.
First match he wins. Lantern. That's the big one in my opinion. Grundy is even or his favor.
He was nerfed but they were the necessary to take out infinites. F2d13 df2 in the corner was an infinte vs a few characters, you could hit confirm into a combo, reset with ice arrow, load ice, continue pressure that leads to +20.
The b23 nerf from +15 to +3, also in the corner it was an 'infinite' to an extent. You can repeat it with out being interrupted and could hit confirm an ice arrow if you had it.
The only thing that was bad about the f2d13 nerf was that it took out a guaranteed reset on hit or block... but he still has b13 on block, 111 on hit or block. Also ice arrow, wiff normal to super.
His buffs were the mb stinger and croutched arrow hitbox.
The croutched arrow hit box was huge in the lantern matchup. Before, it was a trade for an ice arrow to rocket for a punish, now it wiffs and he can punish it. The ice rocket can be punished by a timed standing ice arrow, leaving GL getting hit on his wat down, allowing 2 forward dashes to a punish.
Arrow's short backdash is nice for backdashing b13 too, it leaves you at perfect distance for f2d13, it can be backdashed in the corner too with no room to move back. You just have to read the b13 and backdash.
The grundy mu. I may be wrong, who knows. But I feel he has the tools to beat him. I'll try to get some matches with tyrant at nec if he would like to.
I have more gimmicks for nec. There's always new stuff with this character, it just needs to be discovered.
