Played a really frustrating game last night where my team lost even though we had a solid 15 kills over the enemy team. We dominated the whole game and I went something like 5/2/22 as Skarner and even took one of the enemy's Nexus turrets.
However, when it came down to it, the top AP Teemo got super feed and was pushing 400-500 AP by the end of the game. I bought an oracle and told my team to stay behind, but they would get greedy and baited into shroom traps, which would chunk them for like half their life.
In the end, we took the inhib and went to fight Baron. Unfortunately, we went to Baron through purple side, and my team took three different paths - I went through the most direct path, AD carry went down toward mid and cut in through the path before the mid brush and the AP carry went through the middle brush.
The AP and AD carry both hit shrooms, which chunked them by half. The enemy team saw and rushed to take advantage of this, and with both our carries down to half life and a non-sustain support, we lost the fight and lost the game.
Really frustrating, if the game had built in voice chat I would have been able to warn them not to go that way.
