Really enjoy this game and didn't want to have a single complaint about it but it's clear this game is a major money grab and it's become really frustrating to play it lately. You obviously need power ups to win duels and complete challenges but they only make a huge difference the first few duels then you burn through them in no time and what's even worse, you lose to players using one or two power ups while you're using every single one of them all at once.
