2 DPS teams can easily get high, especially Feral Druid + Rogue, I've seen plently of those teams with 1900+ rating, even some at 2300ish, so it's certainly possible. 1900 rating shouldn't be too hard to get in any bracket if you're really serious about it and work together with your partner(s).
As a rogue that has killed Prince (5 times) and Moroes (15+ times) and never seen a dagger (not even the mindblade lol) the PVP dagger is all I got unless I wanna sit around with Ceds Carver... And there isnt much hope of getting to Vash with a 2-3 night raiding roster... We just got Gruul down.
That's a silly excuse as to why you should be able to get weapons that are equal to Archimonde and Illidian. You're coming out of Gruul's Lair, Season 2 weapons are more than enough, heck, even Season 1 weapons would do, there's no reason as to why you should run around with that high DPS weapons in the start of SSC or Magtheridon.
