I'll save the long rant about what the gambit system is and is not, but active choice was a big thing. being forced to spam said "non-gambit" every 20s is a kick in the teeth to anyone who likes the gambit system.
and yes, any testing aoe aggro, you might as well spam that "non-gambit" every 20s as is your only hope to hold aoe aggro without losing defensive buffs. it's pretty damn hard to even keep up 1 full-finisher while doing anything else too, so thats almost 2 lines of gambits being pointless.
in that >20s window to do stuff next to "non-gambit" (which is also our best defensive buff anyway) you have to somehow keep up buffs hots that are around three hots + healing buff, nine 30s buffs, two 1m buffs and thats ignoring finisher effects. so unless you think you can do a gambit every second something is way off.
but wait! thats not all! thats ignorring needing to aoe aggro (note - only 2 of those buffs aoe at all not including DC), move, target people, stay in combat (we never saw that fixed for BB's), pot, lalalalala anything that anyone really has to do in an instance. BUT WAIT!!! warning shot is one of the best defensive skills you have... weird...
that "brainspace" for maintaining a defensive rotation will end up just spamming hots. nothing else as we don't have time.
