Fan Game Modes

Any game modes you can think of that could be interesting to play for the featured game mode length. Let's go.

I'll start off with,well, 2 strange ones.

1st: A giant free for all mode, like 5-10 champions fighting each other. They get full builds immediately, level 18, etc. Who wins is determined by points; points is gotten on kills and assists. (Kills = 2 points, assists = 1 point. NOW you can get mad at killsteals.)

2nd: Instead of buying items, you buy the individual stats. Like 1 AD = 35 gold or something, and item passives can be bought pretty much at will. Some will be expensive(tear of the goddess, let's get tons of mana.) and some cheap(infinity edge passive at level 1, anyone?). You can buy up to 6 actives on your 1-7 slots, and a trinket as usual. Runes/masteries won't be counted as, well, you can just buy the stats.

Open to feedback, looking for more ideas(rito we still want urf back damnit) and have fun with what you give!

Please note: If it's too different(hide and seek for example) then I suggest not including it. It may be cool, but it won't work probably. I do have one of those in my head, but I can't really say it since, well, it requires a lot of explaining and I have to make a map and too much work XD.
