I did 4 beta sessions for ESO, and every bit of it is terrible. Every time I went back I expected things to get better, it just didnt happen. This is worse than most MMO's when it comes to early launches.
It's trying to be an MMO and an Elderscrolls game at the same time. That is where is flops.
In addition to that, it's trying to be a PC game and a Console game. It destroys the interface in the process.
The only way to make this game playable is to tell yourself it's Multiplayer Skyrim.
Your race locks you into a faction. Which means friends are going to be rerolling all over the place. Unless you pre order, then you can play any race and any faction. (hint, this means they realize this was poor game design)
You take the dreadful interface of skyrim, and make it worse. I assume this is to accommodate console gamers, but it feels like trying to hand-write a paper with your offhand. It's awkward, clunky, and ugly.
The open style of Elder Scrolls is gone. There's a clunky quest system instead.
Heed the warnings. Play something else.
