Love internet tough guys.
Both PVE and PVP side of WoW is really easy when you find a good group to run with. I have killed almost every raid content while was current(before MAJOR nerfs) I have every Cutting Edge Since MOP(when it was put in the game) Still working on Blackhand atm.
I've also been duelist every season(except first season) I have also gotten glad 13 times(Not every season, couple glads same season on different toons)
I've been Rank 1 three times, two of them were in BC(S3/S4) Other season was S11. I don't ever brag about my rank 1, in BC i ran Warlock+healer. My healer had both full resil set and full MP5 set. My cata Rank 1, i ran Spriest/Warlock/Healer(ran 3 types of healers) Both myself and the warlock had Legendary staff+Heroic Cunning+Heroic Lightning Cap. You can cheese hard to get rank 1 with comp+pve gear. Nothing special about getting rank 1 or even glad anymore.
RBG are a joke as well, run comp+what time you run easy 2600 rbg rating. I have every season for HoTA. Highest i've been was 2701. I am at work so i don't have the dates for all the win trading in MOP, so if you got your 22-2400 rbg achieves in MOP, i don't even count those. Even if you weren't a win trader, you would run into those teams and get free points and lots of MMR. Lowest RBG rating i've had at the end of a season was 2398.
You may look at what i've typed out here and say, 'man this guy doesn't have a life outside of wow' and you would be wrong, I work full time, had a GF for all my wow career(she plays as well) and we have social life.
