People don't like memorization. Not everyone plays on PC where you can type in chat to make it easier. I would argue that while shooting matching symbols is not a heavy mechanic, the number of steps required in encounters is high. Three steps on three obkisks is nine, with three rounds of that. I don't think next two encounters are as bad personally. Three steps of pictionary each floor plus a stun and then matching a couple symbols while carrying relics through a few rooms. But the final boss has ten steps just to unlock dps plus buff juggling. A bit much. The other thing people don't like is depending on others in pictionary when we all know despite efforts the universal names won't be universal. Speaking of that some of the names given to them make zero sense in my opinion. Giving a role to everyone is cool and all, but it will generate issues for pick up teams.
