Just some feedback for Zen from a returning player (and soon to be leaving) , though I assume it'll make not a bit of difference. I'll keep it short and to the point.
Ballgroups. Why.
I left GW2 due to the awful handling of their version of Cyrodil, basically it's become a boon ball arena, their version of ball groups. Any feeling of warfare or siege or defending is gone. It's just ball group gameplay that leaves no room for soloers or defenders.
I came back to ESO to get away from that, only to find that ball groups are even more common now than the last time I played. Just left Cyro this evening (along with some others) as a group of 4 ball groups were just zerging everything. I've been trying to get my GW2 friends to join me here. They did some research, heard about ball groups and that's keeping them away (they left GW2 due to this too).
It's an awful design in GW2 and it's an awful design here. Total anti fun gameplay for anyone not in those sweat groups. I want to play proper siege and warfare, not look on hopelessly as people stack and run around like the keystone cops.
Thanks for coming to my ted talk.
