AcyridWandumDepends on how you learn and what you want to accomplish. Personally I find that mge gives me muscle memory for the specific shots that you have to hit in a certain arena, where dm prepares you for general aim more. Dm still only really gives you the muscle memory for the area of the map that you play on.I have on tf2 2700 hours and 530 hours as soldier. I play mge everyday, but now I feel like mge little bit useless and I need something better where I can improve.
Overall I feel like I improve my aim in actual games (scrims, mixes, officials etc.) by playing dm over mge, but it really depends on how you learn.
so if you feel like mge is starting to be useless, and the second option you gave is dm, what's the problem?
