As time before the expansion looms I'm just taking the time to get things done mostly that I personally like to get done. Not that much really left to do that I feel I need to really get done that I really consider priority for me at this point in game now since I stopped playing Beta some time ago.
Argent Dawn reps grind is done which was a big one and a big reason I quit playing Beta. Started leveling up Mining and already leveled mining up to 375 yesterday so that's now done as well also. Its now left to level up Herbalism on my Hunter but servers are down for maintenance so no head start on that as yet.
I've only done the Scourge Invasion attack event once and the quest for one day which was last day grinding the Argent Dawn reps. In that first and only time I've done the Invasion event fighting back the scourge I collected 95 Runes which allowed me to pick up the Argent Dawn Tabard and all the available Trinkets as well and Runes to spare. That was before all the crazy PvP in the area with Alliance and Horde as well trying to tag all the mobs. So haven't done any more of the invasion since I've got everything needed with the Runes. But it would have been nice if Blizzard could have made the Runes turn in for Reps as well for Argent Dawn for those that can use the reps. Do hear if you equip the Argent Dawn commission trinket you can collect scougestones though.
Haven't gone out my way to do much with any Achievements other than what just happens naturally been busy. Most stuff I can do whenever I feel the need or bored in some way though rare. Other thing for me are just priority to do. I've sold off most of my Inventory assets on AH across my 10 personal Guild Banks on my Banker Alts which took quite a bit of time to unload without much loss. But majority of that was sold before I went into Beta as well when prices where much higher on AH Economy. Inventory load is now minimal that its no longer a issue. I had one of our guild Enchanter DE several hundred pieces of geen gear from all my grinds for lots of dust, essence and shards, didn't care much for the money just the mats.
Some those mats will be valuable to have on hand and use leveling up to 80 in WotLK on gear for enchants all the way to 80 like Arcane Dusts, Large Prismatic Shards, Small Prismatic Shards (few) and Greater Planar Essences. And for DK's as well when they are leveling if have excess. I've kept some Arcane Tomes because you will still need shoulder enchants leveling as only thing better in Beta is from faction grind. Instead of DE or vendoring I've kept all lvl 60+ Plate gear and items with str/stam/defense/AP on it because gear like that will go at high price when DK's are leveling up on AH or if I feel the need to level a DK at some point. So have abit of that kind of gear in inventory that doesn't bother me to keep and still valuable.
I think after finishing leveling up Herbalism I can consider all my priority goals all done. Achievements I'll focus on to do whenever I feel like doing them because before Achievements I usually made my own goals and do them as needed and not because Blizzard put them there in Achievements to keep me busy in a time sink of their own. Though they are now their as a achievement guide. But until WotLK come out I'll probably just do dailies not that I need to either or whatever and just Bank more gold for the Warchest. Having more gold on hand is a good thing in WotLK especially as a Tank. But before I do that probably take down my Mac PC and clean everything off my drive and reload everything else and WoW and redo my UI as well.
At this point I'm just in a preparation mode for the next expansion finishing up loose ends and anything else done is just for fun as time counts down for the next two weeks.
