Our RPS is based on crits and Mangle reset procs, then our primary AM skill is based on Dodge. We are the only class which relies almost entirely on RNG to generate resources, and the only one that is solely reliant on RNG after using our primary AM ability.
Warr and Pally flatly reduce damage, and scale up with damage dealt. DK both heals and mitigates damage in the same AM usage, scaling with their own gear. Monk mitigates damage passively, and actively dumps off the excess over time, scaling with damage (and player skill in balancing that WITH avoidance AM.) Bear's Dodge mechanic scales up with luck, and luck alone. When you dump 60 Rage into a skill, there should not be only a 50/50 chance of it working.
While the RPS randomness is annoying, it isn't game-breaking. Most other tanks also are semi-reliant on procs, and that is okay. However, no other tank has a chance to blow their primary AM and receive no benefit from it whatsoever, partially exempting Monks considering that Shuffle/Purifying Brew are used much more interchangeably than the other AM skills.
Because I don't believe in moaning just to moan, I would like to propose the idea of partially unnerfing Agi to Dodge contribution for bears so that we are no longer far and away the lowest passive avoidance tank in the game. In addition, rework SD to no longer increase Dodge, but to provide a physical damage reduction/absorb scaling with player HP and/or Atk. Giving bears the ability to reduce damage taken through this mechanic will be much more reliable, and put us in a desirable spot compared with tanks who are not taking unpredictable spikes of unmitigated damage.
Looking forward to community response, positive or negative.
