it's almost always one sided. Either my opposing team is full of amateurs or my team is full of amateurs. So I decided to make a change and start playing SO mode along with my friend to broaden our horizons.
About that... your chances of running into this situation are higher in SO. Unless some of your friends play SO, you'll find it very annoying to deal with.
Also, what mode are you going to play? TD or DM? What setup are you going with? HP or SP? Are you a rusher/ supporter/ defender?
I don't really have tips for chaser as I don't see it as a mode.
I'm not really good... Scratch that, I'm barely average. I casually play TD and do ps duels when I have the time but playstyle is all about common sense. I may or may not be able to give you some tips.
