Some questions about crit is that what does it mean by the chance when it is a whole number - should it not be a percentage. For the description of crit multipliers it says the multiplier you will multiply when you deal a critical hit; does it not just add on that 'Crit multiplier' number?
You could atleast lower the price of the classes, they are way too much atm and would take a long long time to get ahold of if you dont pay money.
Another possibility is making a 'Rent' system so you can buy a certain class for a certain time for less money.
Before this update you could actually play all classes for free without limitations; now you have to wait some days to play a certain class you want to play which makes the game not really continous unless you have money to throw at a game
