flirt5. Do you have a strong opinion on the differences/advantages/etc between dm servers/mge/offline maps?
Offline maps like walkway, rocket shooting, juggle (and the new denial), I find are more helpful for experienced players to warm up, and for very new players to get comfortable with a mouse & their sensitivity.
For more experienced players mge & dm would offer more chance to improve your 'actual' aim, but even then there are a lot of pitfalls that I have myself previously fallen into.
Mge players often develop intricate strategies with no functional use outside of mge, and use those to get a higher elo instead of actually improving aim & movement. Dm players can often get very mindful of their KDR instead, and will pick and choose fights to an obnoxious degree; like running away if you take any damage to go get a healthkit or wait for regen etc.
If you avoid these pitfalls, I think both are good, but I prefer DM as you get to practice more fast-paced situations against different combinations of classes.
