[Discussion] Does taking LONG breaks from League makes you better?

So what's interesting about my experience with League is that last season, I was possibly the WORST player in bronze. After 9 months of hard grinding for Silver, 350 games and 17 series later, I finally got to silver. When the new season started, I placed bronze 5, expectable after playing next to no league over preseason. What was different about this season was that I found the game extremely easy, and took exactly three weeks to get back to silver 5. But then I thought that there was no way I'd get past that yet, and took a break from February until a week ago. Since then, I've maintained that momentum even after being out of practice for 3 months. This leads me to my question- is it that you forget old habits over long breaks that makes you better at things? Proof: lolking.net/summoner/na/50203351
