I'm cautiously pessimistic about Misty Pandarens and I have a strict policy of never talking about anything when it is relevant, so I am withholding judgement beside the first words of this post and what I said Friday. But let's imagine that hypothetically I was not particularly excited by the announcements and possibly other people were similarly not enthused.
What change to WoW, big or small, would get you excited? I mean resub excited, finding time on your calender excited. I don't mean "I guess I won't unsub yet, it looks good enough."
For myself, I'm going to add the pre-condition that the sub price drops to $1. This is purely to get over my strangely arbitrary cheapness and is not a reflection of what WoW is actually worth. I'd bet that at the current time it would still be worth $15 a month to me. I am not a rational consumer.
I'd like to see massive raids again. While we're at it, old AV or something similar, which mixes large-scale PvP and PvE. That type of content was something I loved, almost a microcosm of WoW, with everything going on in it: rep, questing, PvP, raiding, leveling, even farming for a time.
Dynamic zones. I don't think the unbalanced factions and players would work well with an entirely dynamic world. If we wanted EVE we'd play EVE. But it would be neat to see zones that players could change for a bit of time. Maybe we'd have an outdoor raid to unlock something, like another raid, or a really great farming area. That too, get rid of most daily quests and bring back farming, materials and mob kills, as the primary way that players actively generate income.
