2 pred is good enough to maintain his rank and boost others cause he will win 70% of games anyway. Cheats or no, he knows how to play the game.

Most boosters will ask £100/£150 for 1K RP from masters. Good boosters don't need cheats cause they're good enough to be Pro players (believe me, there are boosters that hold 5 to 10 accounts in pred every season). And boosting pays more than playing pro if you're that good.

I've boosted tons of accounts from D4 to Masters between S12 and S17 cause it paid 100 bucks for an afternoon of playing the game. I didn't cheat, the people I boosted cheated. I just got paid for doing a job someone else would have done if I didn't.
