Like I said, it’s fine if you’re playing fluff games but genestealers are one of the squishiest teams in the game, even with T4 and a 5++ your genestealer has negligible ranged ability and 1W and will fold to volume of fire, which it absolutely will draw being your leader. You’re putting all your eggs in one basket. It may be fine for your meta but I play with mostly marinefags, harliefags and a Tau commie, all of whom have better shooting, better toughness or better saves, and often a combination of 2 or more. GSC in KT live and die by how their charges pan out because their shooting is shit and their armor saves are bad. If they don’t kill the dude they charge or if they get charged, they don’t have the durability to hang around in melee.
