P.S:I have no idea what's so hard to know even for a ¨noob¨ which is how you think of yourself... that champions attack each other aye? if i ping/mark the map and i'm right there, we can attack together, if you don't understand that in this game you must click your champion into another champion and try to kill it, then i must assume you're either 120 years old, or just trolling, either of those can be true at this point ¨Join Date Aug 2013¨ <-- How can you be around Aug 2013 and not know what ¨Attacking¨ means? maybe gank? still, i don't get it, gank is basically a surprise attack among 2+ champions: http://es.urbandictionary.com/define.php?term=Ganking
¨If an experienced player wants to give tips and help to noobs, one of the problems is that there's not enough time at the start or during the match to explain things. Having more time at the start to sort things out just delays the game though and for experienced players just wastes game time.¨
Exact! That's exactly what i'm saying, you don't need that in game, you just double confirmed my point and you contradict yourself while you were at it.
If you need tips/help either make a solid post asking for real inquiries on the forum, Or simply add the player who you think did the best on any match you play and whisper him ¨Hey can you give me some tips¨ it will make him feel good, you will create a bond with another person, and we will start cultivating the social aspect on the community. The level of arrogance in MOBAs is too much, so much that no one will dare asking for anything and will rather remain being bad than to ask for help.
