I would not call Ratchets cheap its easy to avoid, but grab ones can be bad I've said it before and ill say it again they gotta make it so you can not get grabbed out of a roll it would fix most of the grab set ups and its just not right that you can be grabbed while rolling.
I learned from asis that you can jump and then use your air dodge if you skip your rolling action to avoid the grab on wake ups. Still it isn't well known as far as I know, and they should fix it.
What do you mean by Fix it? Also I heard from a few people that your the best Ratchet around. As a Ratchet main myself maybe you can help me get better I've been told I'm pretty good with him but need some work.
I mean fix it as in allowing the dodge roll to avoid ratchet's grab if you dodge in the correct direction. I'm a fairly good ratchet and at they very least there are comparable ratchets to me. I have won against asis a total of one 1v1 game and a few (i think it was like 5 or so, not sure) ffas. (lols) I'm on now, go ahead and add me and i can teach you some tricks if you don't know them already.
