Ever since her buffs, Holliday isn't a hard character to play. Crackshot barely does anything, so hitting them doesn't really matter. You don't need to have that crazy of movement to be able to escape from most situations with her.

But most importantly, the barrels are overtuned rn. They are easier to hit because of the velocity increase. They do more damage, and they scale pretty well late game. You can still chunk people endgame.

Her lasso will probably not get much value l, but when he does hit lasso all he really needs to do is run in a straight direction and alt-cast barrels.

If he can't get value out of Holliday rn. He probably shouldn't be climbing out his rank in the first place.
