The soldier powercreep

If you bring every other DPS down to Soldier’s level (and as Soldier is 12th or 13th best DPS in the game that would be MOST of the DPS)), then you have to nerf tanks because then they would be WAY too powerful relative to the DPS role (they are already the strongest role) and then because tank and DPS damage has been brought down you have to nerf healing so that stuff can die.

So you could do ALL that or you could just buff Soldier.
