I totally agree with you.
In the BETA it was much better everyone was a noob.
People wearing heavy armor for tank not light armor with casting a shield.
Everyone was equal no trains no zergs.
Much better but ESO is doing much updates so i have hope for the FUTURE!
It wasn't an AOE fest in the beginning, because (paradoxically) we didn't know about the AOE caps. Players spread out out of fear of the whole group getting dropped by AOEs. Then we learned about the caps, and people realized that the safest thing to do is bunch up and spam impulse. And thus the zerg was born.
