It's a game, people wants to have fun, and having better model/graphics can be a reason.
I'm one of those who like having a cool character, with cool transmog. (I look forward to the new model)
Why do you think i play draenei? For the racial?
No, i like the animations, the way it walks, the way it casts (Despite the fact they seem to have a broom in their ass) etc...
I play better with a better tmog and with a race i like playing.
When i look mmo-champion to see the news, i try to avoid the lore spoilers (I'm reading quests, yes, because i'm a old Baldur's gate player, so i like doing new quests ), and i look :
- PvP changes.
- Paladin changes.
- New model, spell effects, weapon/gear model.
- Pet battle (I traded my Lightbringer tabard for a rare-pet for example.)
Don't blame people because they like something you don't
