I was extremely surprised to see that Wrathion's Legendary questline - picked up and thus far carried out completely in solo PvE and raids - suddenly veered into PvP territory.
The two quests you get in this current patch (if you've been keeping up with the legendary quest chain) are A Change of Command (kill an elite with a raid group), which I expected, and The Lion Roars, which I did not.
Having next to no PvP gear due to not PvPing regularly since probably WotLK, I was rather apprehensive going into my first Battleground, particularly since I had no idea what the rules were.
As it turned out, I needn't have worried:
It only took 1 round for me to get the idea - hold the orbs for as long as possible - and 1 more round to get a win (coming back from behind, no less!).
Sure, if I was targetted I went down faster than the global cooldown, but it definitely whetted my appetite to get back into something competitive.
I especially liked the arena-style Kotmogu battleground since it's a bit of a free-for-all and can't wait to try the other new one (Silvershard Mines). I've never quite liked BGs like Alterac Valley, where you can win or lose the entire map without having touched anyone from the opposite Faction.
Happily, I've been getting through the dailies slowly and only have 2 more to go - Cloud Serpents and August Celestials - meaning I'll soon have more time for all the things I've been missing, like PvP, soloing old content and starting on that minipet collection. :)
