Ended S3 at Silver 1 ~50 LP, dropped to Bronze 1 due to inactivity, got back to Silver 3 and just played a game a month to prevent decay. Didn't get to Gold, which I would've kinda liked, but I just didn't feel like playing much either, so obviously I didn't put in the effort and thus didn't deserve to get there.
Might go for Gold again in S5 if I find a couple of champions I don't mind playing over and over again(kinda like Zed/Jax in S3/S4), and if WoW doesn't steal all my time.
