I've played the following comps
And we beat EVERYTHING but when we hit 1900mmr, we get more disc/hunter than anything else so it outweighs the rating changes and keeps us stuck at 1900. We can beat 1800 disc/hunter, just not 1900 disc/hunter :| they seem to play much more effectively. Tips apart from rerolling? Any unknown godly comps out there that can beat it? I've honestly been considering Rdruid/Feral or Hpala/Boomkin.
edit: me and the warrior are trying again soon, we've been close to beating these god tier hunter/disc teams so we'll gonna have another go. We also met Archpriest & Lyriat who are rank 3 on our 2s ladder atm, they crushed us as Disc/Hunter so we know we're not getting above 2.3k :d
