I always test on apex bats with geo (idris), cor (regal), brd (max) to ensure I'm capped out in every possible way to understand the maximum theoretical damage of the weaponskill. It cannot get better than this damage.
except with MA proccs. fighters roll is one but on drg that might not be a good option.
Testing on bats I actually have to say these are much lower numbers than I hoped for. Guess ill stick to starting out RDM. MA procs can change your max dmg quite a bit. and the 95% acc has a tendency to skew results on tests.
