If you are with an experienced group you generally have one person designated as the BR initiator and he will have a macro call when BR is started. The group then pushes their BR macro for the set skill and debilitating effect you desire. several different macros among the group for each situation. one to weaken def, another to burst maim or victimize. they can also be combined with magic for other debilitating effects that without question serve only one purpose but to increase damage. An experienced party of 8 shouldn't take any longer than 3 seconds to react to the BR call and put it up. Even the base BR of normal attacks to reduce defense is insanely effective. My maim almost always gains 5% damage (maxed out at 3000 tp for consistency) when the mob is debilitated. The fact that I even need to argue about this is a little confusing.
