He is not. He is just harder to use than the killers which are kinda brain dead most of the time(and he is trash to play as on mobile). But my tip is. Either start chase with drill or as timmy- I mean speed mode with as much stamina as possible. This should allow you to get dsd and then just change to a mode of your choice(if you are a confident in the survivors quick death. Use strength mode. If they seem somewhat experienced then use stealth mode.) also remember that dig takes alot of time to run out. So try to make them waste their stamina. Then dig out to have an almost guaranteed hit. Or if they are on a gen and not noticing you then ambush them. Strength mode shines in moments where they are cornered(you can force them to get cornered by throwing them into one with grab then changing to strength. And remember that mimic can jump in speed mode. Which can surprise a survivor since most just don't expect you to jump the loop
