I like 1 melee in the group. It's good to have 2x short CD kicks.
But yeah, rogue or dks are the better melees to bring.
I don't care if we bring a warr on 15 it doesn't matter as long as dps is enough and kicks are good we time the run.
But sometimes ppl come with 2k io in your group and miss most of their kicks and then you wonder where they got the rating from.
My best runs are actually with ppl 1200-1300 rating. There I saw many almost flawless runs. All spells kicked and great dps.
But rating doesn't mean much. 1500+ means he play good in a group. Doesn't mean he will fit well into your group.
And more and more bad ppl reach 1300 rating. You can have ppl with 3k dps in your group that have 1300 rating.
