Two of my friends used their 90 booston a warlock (because fotm pve dps I guess) and I didn't have much to do sunday so I dusted off my ol' undead. Craptastic 480 itemlevel gear but I had a lot of coins and shit, went and got megalucky from ordos, and celestials, plus had some honor saved up so suddenly I had 509 itemlevel. Why not boost 30 itemlevels in two hours, good game design =P
At any rate, I found destruction way more fun than I remember it (pre-embers) and just kept shooting things. Went to the isle of thunder and killed a rare, obviously it dropped the tome. So I set out to do the green fire quest and boy, that shit was annoying. I feel like the walls in the 'maze' are bugged because even though neither me or my pet touched it at times, it still spawned a buttload of ghosts. Worked my way up to the tower and tried the end boss for about an hour. Went horrible and I went to bed angry. Figured I had some time this morning though and did a nice one-shot so now I cast the greenest of fires. Overall, I must say that questline was really cool and I wonder why they don't do more class stuff like that, instead of crap content no one likes (all the starting scenarios of MoP, for example)
