Why do I keep losing games like this?
Im a Bronze 5 mid laner and in a lot of my games, I get the first kill on my enemy mid laner and I'm out CSing them by a fair bit. After killing them once or twice and out CSing them, I can confidently say that I've won lane and have no deaths (this is around level 6). Now, apparently I'm meant to gank other lanes, but whenever I do this, I either die from roaming, or the gank is unsuccessful and my opponent catches up in CS. Throughout the game, I end up dying more and more and so does my team so that we end up losing the game and my opponent ends up with a better KDA than me
Nonetheless, when I have a decent lead in lane at around level 6, I always seem to lose it, and I'm not sure what I'm doing wrong. I play AP Ekko, and my mechanics on him are much better than the vast majority of opponents I face in mid lane, but this situation always occurs and I don't know how to fix it.
Any advice?
