So I've worked my way up to a higher level of player (TS 2100-2300) and recently fought, and lost to, a TS 2400 player. Only once have I seen an IG player builds Cats and he was the one I beat. Everyone else utilizes a three GM, one Sentinel build regardless of hero.
So I have to ask, as a non-IG player, is something wrong with the Catachans unit? It appears that the power cost is too high for players who prefer to avoid most power costs in order to fast tech into tier 2.
