I ask, because it sure seems like it. All of my characters get stunned from time to time of course, but it seems like it happens more often to the Guardian, the guy wearing the heaviest armor. Am I imagining it?
So, there are more chance to get stunned by them. Especially in ROF instance.
Indeed, it´s a PITA if you have to do RoF without a LM. I wish we had some shield or "shield spike/buff" for this, stun immunity chance increased by 10 / 20 / 40%. RoFT2 without LM (1st boss), can be a PITA, especially if the tank does not have TTT-legacy (5min cd without it).
