My blood elf can get blue eyes -
New lands - meh - we get them all the time - without them i wouldn't even consider it, you have to have it, but the area doesn't fascinate me.
New systems - meh - if it's more like Legion i'll enjoy it. We always get new systems, and they try to make improvements, BFA stepped back, this seems better but it wasn't enough.
New story - i wanted stuff on the races, not weird death lands, but hey it's something different so okay. Wow's story is patchy and inconsistent, the best part about their lore is the races that have a lot of untapped potential, I'm just not interested in following singular characters and not having real depth - not enough depth to draw me.
Incidentally I am aware of a few people who are coming back to wow because void elves can be high elves now - and that was their only reason - not sure how they'll take not getting blonde hair though.
I'm pretty sure mine is the most extreme reason. But at this stage I'm seeing more people returning for very superficial reasons rather than core reasons. what does that say?
