Just so you’re made aware
Groups are empowered to manage their own members through the vote-kick system. If the majority of the group feels a player should be removed, they can initiate a vote-kick to remove them. The system is entirely under the control of our players. Players may choose to remove any other player from the group for any reason, provided the vote to kick passes.
Customer Support does not provide loot, gold, or quest/achievement progress not gained as a result of being kicked from a group.
From one of the same threads I’ve just linked:
Customer Support can not provide anything if you are removed from a group, as stated by the Support Article.
How ever, if you wish to provide feedback about the vote-kick system, might I suggest providing that feedback via In-Game or the Dungeons forums?
