crawdaunt is a good pokemon, no doubt about that, its an excellent DD'er and choice abuser, but it has a few downfalls that prevent it from being suspect worthy.
For one thing, crawdaunt is relatively frail compared to other Dragon Dance users in the tier,(feraligatr, fraxure after eviolite, shelgon who ive wanted to try for a little while)making it significantly harder to set up, its physical defense isnt so bad, but most special hits will at the very least 2hko it, and unlike the banned durant it lacks significant resistances and has a weakness to hitmonchan's mach punch.
another reason that crawdaunt isnt broken is that even AFTER a dragon dance, it is still rather slow, only being able to outrun base 105's at best and being revenged by literally every scarfer in the tier if it doesnt have a sub up, sure base 105 is fast, but key threats such as galvantula, sceptile, and scolipede still outrun it, and hit it super effectively.
although, maybe im underestimating crawdaunt's bulk? can you provide some calcs of crawdaunt taking reasonably strong hits with enough hp to sweep or avoid being revenge killed? ive always wanted to try out crawdaunt tbh, its a really cool mon and has a lot of raw power, but i cant imagine it being broken.
btw sawsbuck is still a beast in RU despite recently dropping to NU, take into account that its main revenge killer moved up to UU at the same time, and how hard it is to wall sawsbuck, along with nature power bypassing absol's sucker punch, which is really awesome in a pinch.
edit: crawdaunt has a resistance to sucker punch which can come in handy, i guess
