I ran across this today and it explained a lot to me why I get diminishing enjoyment out of this game after levelling up the first toon. For me the quests were fun once, but trying to be "competitive" either in PvP or PvE means you have to grind, grind grind, grind grind. New patch? Grind some more because your build was nerfed.
After watching this video it's almost like there's two teams of developers for ESO: one group makes fun stuff and the other group makes abortions CP, loot tables, weighted RNG, grouping tools, etc.
