Going to have to step in here, and state that you are factually incorrect. I'll ignore the pointed words used in order to give yourself some level self-importance. RNG plays no part in the fact that a PLD with str gear equipped, which your off-tank should be,can catch up to the main tank. When the main tank runs into conflags in order to avoid unnecessary damage, combos will be interrupted. This combined with the fact that the off-tank is doing more damage with dps gear on, and that he gets more RoH in, he will be catching up, not necessarily 100%.
So please, stop trying to make yourself look important, and either add to the conversation or sit on the side-lines.
