If you're pointing to the 1 Hit Kill version of the Snipers ..which happens in the real world..you're also pointing to K-Style which is NOT possible in the real world.
If ever 1 or 2 Hit Kill snipers are implemented in gunz, I'd want the characters equipped with snipers to be slower when they walk/run and increase the weight and no jumps or wall runs or tumbles.Maybe make snipers map dependant or game mode dependant.
Things cannot be perfect for everyone.
and here i quote "What does not kill you, might kill someone else"
