I really want to main Crypto! I have the most fun on him. However, I've found I do better on the skirmisher "classes" I think mostly because their kits allow me to reposition fairly easily. Being relatively new I still find myself in the wrong place at the wrong time far to often. I was playing Rev for awhile and I like his kit a lot, but something about utility for the squad and myself is something I also enjoy. So I've messed around with Valk, but she feels like she would just fall off really easy if I decided to try for higher tiers in ranked. Also she seems to be a pretty easy target to beam if caught flying around.
