Criticism of Shadowbringers and the hostility there in

[Nezerius]

I disagree, a game can always take ideas from other games and improve them and use them to greater effect. In Fact if you watch the no clip interview, Yoshi-P had his dev team play WoW, and a lot of systems in XIV are older systems from WoW.

It's entirely dependant on which ideas are taken. Some ideas would be good (changing the glamour system to be similar to WoW), other ideas would be bad (Warforging/Titanforging from WoW).

The ilvl for example is something used by almost all online games now, it was originally an addon for WoW known as gearscore, they eventually hired the guy at blizz and it became a full on feature.

Kinda nitpicky, but iLvl didn't originate from gearscore. It already existed as a hidden number on an item's tooltip, which could be made visible through the GetItemInfo function. Gearscore simply used this hidden number to create an overall score for the player's gear.
