Team mates refused a gank
So today I had a game as a jungler (Sion). When I thought I was ready to gank, I first pinged top warning them that I was coming. However he pinged me not to with quite a threatening message saying that if I push his lane he was going to beat me with... (I forget), so I was like ok, he doesn't need it because he was actually getting fed. Then a few minutes later I stayed in the bush in mid to gank, but again I got a ping. I thought, ah maybe they didn't need it yet. Same thing happened with bot, I hid in the bush then it was the ping again. That was really annoying me. I left. Then ez from bot said, I thought you were gonna gank? (Facepalm) I explained but they didn't reply. After that, there were 3 enemies bot, so I joined in, just trying to help. I admit I killed minions there too because I thought they were a bother, then ez came crying to me saying I taxed his lane and that he was behind because of me. So we lost the game and ez said it was my fault. That game gave me a rotten mood. Can I get some pointers, my dear friends? Thanks
