ESO has various issues which I think gaming sites who are pre-disposed to hate on it will do so using the following criticism....
1) It's not "finished", no justice system, thieving, brotherhood. (It's an MMO, they're never finished)
2) Non-traditional End Game: General impression that end-game is PvP. Adventure zone concept is confusing. Like the Wii U debacle, where people thought it was an accesory for your Wii ---- people being confused about your product is never in your favor. Zenimax should've released video of Craglorn.
3) Major feature Anchors is like a rift in RIFT. Response: So what? It's a story element.
4) Skill bar/Menu condensed for consoles: True, but reality is not everyone wants to have 80 keybinds and 50 bars on their screen to enjoy a game. 12 abilities plus the heavy/light/block/dodge is good enough for me to master, while not making it a job.
5) Group phasing: This is a very legitimate gripe, IMO.
6) It's not like Skyrim: Can't pick up everything, shout at angry bears and make them fly off mountains. Never seen so much general, unreasonable hate at something so unworthy of it.
Problem is they just wont look it what it can be, will ignore the ridiculous amounts of polish the game has and instead will cherry pick criticisms and give it a 7ish, IMO. While rehashed Mario Bros 43, Japanese 90s RPG rehash 15 and Pokemon Fuscia all will get 9.5.
