The problem you will face when another person ranks your chaos account 'for you' is that every time you actually play your account, you'll face oponents matched to the rank of the account, not your level.
This means you will
1. face a very long wait for a match, as often there are not many high ranked players online, and it takes a long time to match a lower player, this can often take 300 seconds to get a match, even more sometimes.
2. face opponents much better than you, and lose almost all matches you play.
3. lose lots of ranking to players of your ranking or better because the account ranking is much higher, each loss will count heavily against the account ranking.
4. probably be pressurized by the high rankers who 'helped' you because you'll lose the ranking they gained 'for you'.
These will probably combine to mean you will actually be paying for chaos, but unable to actually enjoy playing the game.
Just saying; THINK about it.
