Perfect, now let me and my friends all roll healers with a few melee and we will faceroll the crap out of you without CC stoping us.
It wouldn't be any different from what is happening today with all the stuns, roots, slows, CC, and other means to keep a player from functioning in a Warzone.
However, you neglected to read the fact that for 30 seconds, everyone is vulnerable to being stunned, rooted, slowed, CC, and otherwise inhibited from acting. In anything there is a tradeoff. However, in its current form, the resolve system along with the plethora of abilities to stop players from having any actions is simply broken in its current form. You may disagree, that's fine. But I would venture a guess that you have had your share of stun locked deaths to the point of frustration too.
