I took my 5* up to r4 immediately after I got her and 5* wasp from featured crystals. I don't use her as much as I probably should though. I know how to use her, but can't get a handle on the phase intercepts that I see in videos. Seems like in all these videos, the opponent constantly attacks and misses into their phase. Every time I try, the enemy backs up and sits there. Guessing that has more to do with strange AI behavior lately, but same thing happened before this.
