I've seen a few that I would have liked to alt/F4, but like what has been said earlier we all had to learn. Harmless play is one thing, but you would think that after having his head handed to him a couple times the individual would ask for help or go to the tutorial section and/or training to accquire some experience. I have noiced that there is more activity in the training & dueling areas since the closing of the "FREE ZONE". Possibility some of those ***-** bought the same habits from H2H into the pay side.
Now, don't go bad mouthing us H2Hers
H2H was an entirely different environment, and you would be surprised how much people asked and learnt there.
There weren't 150 people listening to every silly thing you said, and more often than not all questions were answered. And yes we did have a few ALT+F4 guys, but even amongst eight people there was usually somebody who replied correctly.
Its surprising to me that when a newb question is raised, out of 150 people online, a few answer "ALT+F4", maybe one or two answer "Go to training area" (which we all know no ones gonna do at that point), and almost never does someone ever say: "You do that by ________; you should try the training area, it really helped me a lot".
Of course as stated already if you don't know what ALT+F4, Win, Win+D, Win+M, Win+Shift+M, CTRL+ALT+DEL etc etc. do then imho you need to learn a bit about windows first...
