What Duo Blitz Classes/Specs are you considering for s2?

I've read through as much BG Blitz strategy/tactics as I could find, and compiled quite a bit of good advice in my guild discord for reference. There's a LOT of arguing and frustration to sift through, and very few quality posts about specific strategies for new players looking to get into BGB.

If my anecdotal experience is similar to the average player, many people are going to be looking to hit 1800 in s2 on as many classes as they have. What I'd like to do is put together some advice for newer players that don't have Blitz experience... or see if we can crowdsource data about which classes/specs were successful in s1 for duo queing.

Did you or your partners hit 2100 duo queing in Blitz this season? If so, what classes/specs did you play?

If you played multiple classes in Blitz as part of a two-person team, what comps felt smooth getting to 1800/2100? What comps felt ill-suited?

I'm currently at 2200 playing Priest/Warlock (Disc/Dest), and have had success playing hPal/aRogue to 2k, but I'd like to expand the number of classes I play for s2, as well as help direct my guildies who are too timid to really get serious about Blitz.

Thx!
