You are not realizing that it all depends on how you match up with your opponent. Just because IIB may be able to beat any clan in the game, doesn't mean they are the most skilled. Since they are so high leveled, they can never be significantly outmatched.
I would posit that based on the objective data, Reddit Troopers is a MUCH more skilled war clan than IIB. Reddit Troopers (and I'm guessing it is the same with other similarly leveled clans) faces clans that are MUCH higher level/more advanced than themselves and win. Is there any clan out there that could significantly overmatch IIB and provide a similar challenge? (Not trying to troll here, I'm legitimately curious)
