1) I want some world pvp. I know a lot of you hate it but I don't care about you. I stopped playing in early cata but it seems from what I've read most people just either stay in org or Iron forge. I have read that the next expansion will be more focused on war between the factions and this is intriguing to me but most of the world zones are forgotten or empty. I think wow needs a daily world pvp event that happens where it would be a call to arms during a random peek hour of playing time. Most of the major cities and immediate surrounding zones in wow are empty all the time and I think this is where blizz should base these pvp events. Imagine your sitting in Org and the faction leader shouts out orders to attack Darnassus or really any random city or even a town, could even be in outlands. At the same time the Alliance would get a shout out calling for defenders and maybe each city would have a portal open up so that people that want to participate in the event can get there quickly. Give each side random objectives to try and meet to succeed in the attack or defense based on the zone terrain or whatever and let the battle happen until one side wins. On servers where there is a faction imbalance maybe give some kind of WG buff for more healing or damage or maybe the side with less players gets help from a giant world boss type NPC like in old AV. If people don't want to participate they wouldn't have to. Have it be totally random what zone it is each day and which faction is attacking or defending.
2) Professions need some love. I really liked in BC where as a black smith I could make a nasty mace like deep thunder and then when the next tier came out you could get mats to forge it to storm-herald. What I would change is that instead of having the mats only drop in raids also have them available by doing solo profession daily quests but make that take longer. That way players that don't like raiding could still access top gear by questing/adventuring etc. People should be able to craft entire armor sets if they like that is on par with raid progression if they are willing to put the time in.
