The only annoying thing about MNK imo is the fact Thunderclap needs a target. It should work like dancer's dash where it just dashes forward if you have no target but if you have a target it dashes to them. Though personally I would prefer to have it work like DNC's dash as switching between targets on a controller is very tricky especially when you consider that you use the dash at the last minute. Unless you drop a gcd or take the hit it's near impossible to target a party member outside of a point blank aoe at the last second to maintain uptime.
