Inq is definitely a hardcounter, and completely unbalanced class. I am a new player to the game, and i have only played as Inq once. i found a MU n1, and i killed them n2, and won the game. WITH NO EXPERIENCE.
classes should require at least a bit of skill, rather than just being able to win easily and before the game has ended (except fool, and other classes like that, which do require skill and remove you from the game upon winning)
However, Inq is not the only hardcounter class.
These are not hardcounters, although i would agree that they do only negatively effect the cl/mm. This is because they prevent a convert. This gives information to the cl/mm along the lines of " i couldn’t convert them. they may be prince, neutral, or have the favour of the king/cw - they are important" They punish the unseen/cult slightly by reducing their numbers, but have no other effect.
Smite however, Instantly kills up to 2 cult, prevents 2 players from being converted, and can permanently handicap the cult, making a bd win all but inevitable. This does more than almost any ability in the game. and it can be used twice. No other abilities can have this much effect on the game - and this makes it especially overpowered compared to it’s counterpart the sheriff - who shares a single ability and has an almost pointless ability (which does little more than confirm the first ability), as well as a day ability that can gain information from unseen visits, leading to possible executions. Note that Scout does not kill the mm if they convert, and that there are defences to being visited (Scorned target, convert immune, a different ability was used, etc…).
