I think more balanced stats would be something like this. I think a sniper rifle meant for taking out buildings and ignoring resistance is good, but I feel like it should have proper downsides to go with it.

Pro: +Ignores damage resistance (must be fully charged)
Pro: +50% damage to buildings (damage scales with charge)
Pro: +Shots slow down target (Like natacha, always lasts 2 seconds, but slowdown scales with charge)

Con: charges 25% slower
Con: shots leave a team colored tracer
Con: -10 shots with primary weapon (was thinking -15, but only having 10 shots might not be enough)
Con: Player moves at 1/2 the normal scoped in speed.

Thoughts? I figured this might be more balanced, but I want your input.
