I got pretty mad last night. I'm only lvl13 so my experience with the game is rather limited, but anyways...
Went 3-0 against Akali during first 7 mins or so on my Ryze in mid-lane. Other lanes were failing pretty badly, though luckily they had not fed too much at that point... I thought that it was all good and that I could carry late-game as long as I got a few more kills...
Thats when the shit hit the fan. The Akali started ganking top and bot like it was nobodys business and was suddenly 10-3 with me still being only 4-1.... And after that she just started snowballing like mad. Our laners fed her like mad and even I got killed quite a few times whenever I tried to counter-gank as whenever she "got into trouble" she would just use her invisibility thing and run away or 2/3vs1 me with the other laners.
Luckily the game did not last long as she pretty mucb single-handedly obliterated our team after racking up like 30 kills or so
Heard later that I shoulda just gotten an oracles elixir as the first thing when I saw her getting the first few gank-kills to counter her stupid invisibility... The more you know :P It just seems to me that Akali is the ultimate noob-ganker. Cant get away from her and cant kill her before she has used her invis.
