For this first one:
We had a terrible laning phase where top exchanged kills too often, and bottom kept getting pushed. I was denied a bit in mid, being forced to use Q to last hit. Our jungler was terrible and didn't gank my lane once even though it was pushed every wave.
Good thing we got the first tower on top, and I got my first couple of kills near dragon when Taric and Irelia dropped in a small 3v3 teamfight.
In the end, we got Baron, killed 4 of them for no losses under their tower, and took down their nexus.
