I just had a Nasus top, who I ganked for early cause he was against a Vlad, who then afterwards would continually try to fight vlad and then just get out sustained cause he started Doran's Shield then rushed a Tri Force. Didn't even bother with stacking his Q.
So even though I had just ganked for him and both mid and bot needed help (cause every lane always needs loads of help in this ridiculous silver ELO), he then spam pinged on top of me and said I HAD to gank for him again. I calmly explained to him that all he had to do was farm and build MR and that I had to gank the other lanes. Bot lane was after all already flaming me as well, cause welcome to silver
"Just getting your second buff and recalling after a successful gank top side? YOU SHOULD HAVE GANKED BOT TWICE ALREADY! HERPY DERPA DERP!"
Anyway, instead of doing the normal thing and playing safe, warding, and waiting for me to make the rounds of winning every single lane for my team on my own, he then says the typical "if you don't gank in 2 mins I'm afk feeding at 20." My Zed was luckily the only other mature one on the team and tried to back me up, but by doing so Nasus flamed him for a bit as well until Zed gave up and muted the kid. So, I go to gank bot and we get one kill and then a dragon, Zed even managed to force the enemy Talon off the tower so we head mid to force it down quickly. Meanwhile top Nasus over extends chasing Vlad past the minion waves for no reason and Olaf shoes up, then instead of flashing out and running from the lvl 5 Olaf he tries to 1v2 them since he was lvl 6. He dies and preceeds to rage up a storm like I have not seen in a very long time, all directed at me personally and how I'm an awful jungler and he was for sure just going to troll and feed now, all cause I wasn't there for the counter gank... and got a kill, dragon, and tower with my team instead....
He then continued to do this for a few more minutes, just none stop harassing, it was so bad bot lane even shut up and stopped harassing me, cause I was doing perfectly fine and they didn't have much reason too anymore and Nasus was dong so anyway. I then muted him, told him I would, and I guess after finally realizing I wasn't just saying it he started to feed on purpose cause "my jungler was completely useless!" As he put in the end game chat.
So I feel your pain, and only the enemy Vlad stuck around to report him with me, even my own team all left instantaneously, so I doubt that childish Nasus will get enough reports to warrant a look, at least not that match, so for now he's prob going to get away with it.
People are just generally pathetic, and for some reason this game brings out the most pathetic side a person can muster. No idea why, but it's all too common and not nearly punished enough.
