IR just increases the chance you will crit, not how much the crit does so the weight on crit would be the same regardless of IR being on or off. I leveled both tanks first so I'm not sure on DPS stats, but I assume critting is 50% more damage? So a traited IR would basically be like a 15% damage increase. What I'm looking for is what someone posted about DRG rotations, it had the weight of each stat like weapon damage was 7.52, STR was 1, Det was .22 etc. I'm trying to see if I 5 meld all the crafted ilevel 55 pieces can I out weigh the Darklight gear, I have about 1800 philo so I can get all the Darklight accessories + belt.
