So ... ive looked around, not found anything regarding this.
I've toyed around with the different 63's...
Ive found that getting 300 acc, 214 crit and 300 surge leaves me with exactly 1000 power (using 3 power augments).
However my ranged crit chance dips down to 32,5% instead of 35% (+15% with the old BM railshot bouns).
Any other PT pyros out there that can give advice?
