Wow, we're in VERY much the same boat, Kawai...except I'm the big bear butt you see just a couple rungs up the ladder. Sorry about the view. I grabbed Idol of Terror with my first set of badges, and I love having one piece of gear that's the same as the leet T6 tanks almost as I love the agility boost itself. (actually, two pieces since I bought me some
boots of natural grace last night!) I now have 20ish badges and am working for more in any heroic, with a preference toward anything Coilfang to finish off CE rep for my Earthwarden (two more runs left!!!)
I have a
similar subpar cloak. I'm locked in at one ring slot with the increasingly awesome
violet signet from Kara and a decent poor man's second in
iron band of the unbreakable.
So as has been pointed out,
Idol of Terror is your first grab, no doubt about it. It procs
all the time giving you a very consistent increase to ap+crit in cat form and dodge_crit in bear form. You will NOT be dissapointed.
From there you and I have tough decisions to make. You know all this from Emmerald's list, of course, but I'll net out the options as I've got them organized in my head.
Ring of Unyielding Force is SO tempting because it's a kickass ring for just 25 badges, but it's a bit of a red herring because the best in game tanking
Stalwart Protector ring awaits at 60 badges.
Then at the cloak slot there
Slikk's Cloak which is admittedly a steal at 35 badges, but there's some excellent and
theoretically (i.e. capacitus HATES me) easily-available placeholders off
first boss in regular or heroic Mech,
mid-Kara/Illhoof, and
last boss of regular MgT.
I'm going to be bear-y patient and save 60 badges for the best tanking ring in the game, and to get me by until I re-save up for Slikk's cloak I'll run MgT when the opportunity arises for a shot at the cloak I really want, and one of these days I'll con guildies into farming that ******* Capacitus on regular until he drops my cloak.
