Remember the good old days when as a stealther (Scoundrel in my case) you could ninja cap a turret in civil War.
You know how it went, sneak up, Tranq Dart the lone defender and begin capping. The defender breaks the dart CC and you reply with Flash Grenade. Now, with their CC breaker on cooldown, and with them therefore out for the full 8 second count, it's a job well done for you, turret taken.
Except, of course, when 1.4 bubbles are involved. So following the scenario above what happens. Well hey, no problem for the lone, bubbled sorceror because even though they are supposedly stunned full the full count on your Flash Grenade, having blown their only CC on the dart stun, there is always the magic "off button".
Just toggle off the bubble and flash, wham, one stunned Scoundrel, me, thus ruining the otherwise perfect ninja cap.
Seriously Bioware, this ability to toggle off bubbles for stun effects, even whilst the player is stunned needs to go.
Um.. Hybrid Sorcs have always been able to click off their bubbles while stunned. Only change is its a stun now instead of a mezz. So no difference in that scenario.
