Thing here is folks are treating the whole RNG of the 4th positional like it's gambling at Vegas.

It's a 50-50 chance ONE of them will pop.

Other jobs like BLM, BRD, even WHM have such low RNG percents. SCH and SMN also experience this with crit procs for their pets as well as their own damage. So when put things on a macro perpsective, you put DRG's 50-50 proc ratio against all other jobs, it seems very very trivial. Moving slightly to the left or slightly to the right isn't such a difficult thing to do, even with some melee mechs from the boss.

Everyone is seeing the potency and procs as a cup half empty that is punishes players. I'd offer, see it as a cup half full and that these procs reward for greater dps. Do other jobs not get punished for not being vigilant on their own mechanics and procs? SMN dots fall, BLM procs, etc etc
