Leveling up a level 6 smurf account to 30

hellu?

invest $5 buy the 50 win xp boost and the 3 day xp boost. win a bot game, win a pvp game, win a 3v3 bot game and win a 3v3 pvp game. compare xp gains. average xp gains over time played. pick best mode and spam.

I think 3v3 was nerfed for xp gain. best bet is to check on reddit which mode is best for leveling.
