So I have finally done some experimentation with the merits of levelling in BG's.
Here's my Shaman's achievement list from yesterday. I managed Damage Control after three AV's, the Grim Reaper and Class kills came from the first. It took me several weeks of play to pick Stormpike Perfection up on my Hunter: that came from the second AV of the day. I was getting invites roughly every 5 minutes: each tower destruction or enemy target awarded 18.5k XP with Rested. Yesterday I did pretty much a level in an afternoon (Rested bonus plus two +10% XP items). In the group there would be 2 or 3 L80's, the rest were 71+, and it was INSANE, but in the best of ways. At one point I was one of fifteen people in Iceblood Tower trying to beat off a particuarly insane L80 Pally. Healing spec really paid off, my regen was pretty good and clearly I could do the big numbers over a reasonable battle. Only when the German server group turned up did I see anything like an epic fight, and that only lasted 35 minutes. The rest of the time it was quick, clean, and pretty much the fastest levelling experience I've seen.
Suffice to say I'd bet this XP level will be nerfed by Blizzard at some point, because I reckon it's giving an advantage to people levelling via this method. If you want to advance using PvP, make the most of it!
So, I've done Koralon in both modes with the Hunter, and even with 25 it's hardly difficult (though saying that I would not want to heal the fight, the potential for stupidity really is very high) We had the dreaded 1% wipe with only my second PuG, and he died next pull. It took a LOT longer to grab the achievement with Emalon. I've seen Rogue loot drop from 10 and 25 man a LOT, and yet again last night there were no rogues around to sweep it up. Where have they all gone? :( Happy though, 226 hunter gloves are now MINE, 3/5 tier also dun. IoC was yesterday's BG daily as well (though still need to complete it) but this did give me a chance to do some Achievement sweepage. Back Door Job ftw! (fnar fnar)
This week I will look at the other BG's with the Shammy, but I'm betting that none will do the job as well as AV for instance XP. Plus, there's the small matter of the 25,000 HK achievement on the Hunter...
