Same here. Will NOT spend a single card or token on this one. Eariler, I was thinking of taking it to Max 5555 but I'm not sure I should spend credits on this one or not. I have left with only one free upgrade. I will try to go as far as I could with Max 3535. If I could find time to farm credits, then only I will think of taking it to fully Max. But surely will not spend anything on pro upgrades.
