Main reson i wonder. My guild is going to do the Trials, most of our players are V10 but the ppl that are V5,6,7 etc, are wondering if the even can enter aswell?
I would assume they'd be able to enter. However, they would likely prove to be a liability to your group due to lack of gear and lesser health/resource pools and DPS.
I don't plan to bring anyone under VR10, preferably mostly VR12, into Trials when my guild starts running them.
