Things i predict will hapen in 6.10 and onwards

1). Olaf who currently is under the radar(Ghost buffs, W buffs, BC cost decreased - everyone else nerfs) will make people realize how oppressive will be in lane, if played right

2). Hecarim back in meta

3). Ghost+Flash combos on lots of champions

4). The comeback of Bloodrazor junglers*

5). Kindred insta-win vs. 2+ tanks teams in 6.10 + nerfs incoming in 6.11

6). Changes/tweaks to AP mages will continue in 6.11

*People need to realize the low win-rate of ex-Sated Dev abusers champions is due to the fact that a lot of them were used to a different approach until now (#1 priority was to get sated). They will adapt soon to the new jungle item. They will find new builds. They will change their playstyle. And when that will happen, you will see the that the win-rates of some champions will sky-rocket with the new buffed Bloodrazor. That's the reason RIOT didn't buffed any of those champions (besides Yi who was mega-nerfed around the Sated Devourer). Belive me, i've seen it already.
