I like this idea. I know I could definitely benefit from some guidance other than "OMG U SUK".
A couple times I've been in games and it must have been pretty obvious I had no idea what I was doing, but people have offered a tip or two in a mostly constructive manner. More often than not though there's only silence, or if I'm on a team with a "pro" I'll get the "OMG" type responses.. lol.
It'd also be nice to find some sort of "Newbie Guide". Maybe there's one out there, but I haven't found it yet. I've found guides for specific characters which can help a lot, but a more general guide would be great.
My two greatest hurdles are that I just can't seem to get myself to run away in time and that I also like to play a bit of this and a bit of that. I get so focused on "Oh he's so close to dying!!" that I don't notice someone teleporting in to finish me off or I stupidly get too close to their tower or something. Trust me, I have a permanent mark on my forehead from me slapping it. And I like all the different DGs and like to try new things, so I haven't given myself time to really learn one character before trying another.
