I mainly play CM. Hate on me if you will but I don't get a lot of time to play and theres already a helluva lot of elitism in CM, can only be worse in NM.
CM is a helluva lot easier than NM, but when you just want to play for fun and don't really care CM any day. NM takes more skill to succeed (for example you die you lose gold plus farm plus your lane, CM you just lose your farm and lane). CM lets you scale up faster and makes it very easy for decent players, NM takes more skill, strategy and patience. Personally I am OK at last hitting, but not at the same level as the 1800's players and I don't have the time to spend to get my game to that level, so I play CM for A BIT OF FUN.
I got pretty many CM games played, played em' when i was tired of hon. The good thing is that u lane like 10 min then just gank and fight, kinda like midwards, u need to play it to not get tired of this game. tho started to play more normal mode now again and theres no problems. but way more boring haha
