X13 and Basilisk are both banned in ranked now, basilisk was almost as bad as the snakeshots from WZ1.Not just sweats. Pistols can be used underwater (and on ladders) where as SMGs and other guns cannot.
Ideal for swimming around and killing people from underwater instead of having to surface to shoot (SMG, AR, LMG)
X13 is even being used quite a lot as provides enough firerate up close and can be used underwater, plus a pistol saves a perk (i usually switch to tracker to replace overkill) mainly run doubletime, tracker, fast hand, high alert on 2nd loadout. First I go doubletime, overkill, fast hands, high alert
