Wanted to give my 2 cents as a 2400 rsham in soloq. Basically posting here will get u responses like that guy above who has no clue and is saying that soloq is all rng and loterry and that 3k rating is same as 1600. IF u get 3000 rating as ANY SPEC, i don't care how op or what spec it is, you are a legendary player. Ok now to the topic, basically enh shaman is a really good spec for soloq its not even close to being hardmode as ppl above suggest, its arguably only slightly worse than warrior. The way u climb soloq is by looking at the different team comps u get and what u fight against and what is the best tactic to go about it. As u said getting a disc priest VS tsg is miserable and most likely will result in a loss if u dont have a good comp to peel for the disc, but even then if u see u have a disc on your team and after the gates open you are vs warrior dk, try to rush first and make them go on you or try to snipe their healer first before they kill yours. And once u play enough games u should get a feel for what u need to do in every matchup who to focus what to peel when to play defensive... after a while u can even give suggestions to your teammates after u learn the interactions between the comp u play vs the comp ur enemy team plays, on who to CC who to focus, where to play on the exact map etc. And every new milestone u reach rating wise u stay there and farm the appropriate gear for that rating and eventually when u hit 2050 u should be BiS geared, and after that since u no longer play for gear you will be more relaxed and focus more on strategy and mistakes and u should be able to get 2200-2400
