Pictures of a score board from a random bg is not a good indication of rets prowess or viability in competitive rated play. PERIOD.
When put into a scenario where your vsing equally geared and skilled only then do you get a true indication of rets shortcomings as a 'viable' spec.
Running around in a random bg smashing people in blues and greens, half of which are bots.. Like I said does not mean ret is powerful.
either way you didn't earn that rating.
Not to mention there's a large flaw in your story..
First of all, your low mmr would have brought the teams mmr down, admittedly if 9/10 were 2300-2400 then your low mmr wouldn't have dropped the teams mmr by a substantial amount but still..
Secondly you had a gain of 500 points in 5 wins and 1 loss as you claim..
The flaw in that is the higher your rating got closer to the teams mmr.. The less points you would have received per win. While possible.. It's doubtfull.
Lastly, i was in a guild full of 2.2k players on frostmourne and I am now in a guild of ex R1 players, R1 players alts, glads and many 2200 players..
I have also run rbgs at 2-2.1k mmr.. The simple truth is,you would have been vsing other teams that were 2200-2400 mmr and at that rating, 1 weak link at that mmr is a loss.
Cadinbrie - while it's possible, tho extremely unlikely, his statistics don't lie;
370 rbgs played for 200 rbg wins and his highest rating was 1700.
All of a sudden in 1 nights he's gone from 1700-2200..
If perhaps a T2 arena master player got that achievement.. I wouldn't question it..
For a 1500 arena player and a 1700 rbg player..
You sure you want me to do you next? :P
