I believe they will allow cash purchase of playstyle boosters and give some as a reward for event completion. At least cash players can fight it out with multiple account gamers. Probably might make the event hard to complete by scripting certain matches to drain tokens from players who really want the boosters.

Not going to use any playstyle boosters till I know we can get more. How I use them depends on how we can attain them. They might end up being more precious than tokens.
