So, had they not implemented glamour in WoW you would have stopped playing? I find that hard to believe. Never played WoW myself, but sounds like it would have been nice if you had features in you visual settings you could adjust like:
1. Show effects of all glamoured gear set by other players.
2. Show effects of glamoured gear based on level range (60-70; 70-80; 80-90) where each level range has a different default set.
3. Show default glamour set for job class (healer, tank, dps) same gear set regardless of level.
Again, these are just examples and completely optional features that would affect visual effects on the client side (your monitor/tv) only.
