ovoon: The game is too addicting. And yea, you can use real money to buy skins for your character, just to look cool and support the company. Thats about it.
KavazovAngel: Great. So there are no disadvantages? Like, there are no things like buying new heroes, new items? Right?
(I read somewhere that the game might have microstransactions, whats why I'm asking before I make an account.)
It does but think about it like what TF2 has now. You can get the items you want given enough time and effort or can just go and buy them while some of the cosmetic crap like recolors or different themed skins that give no real advantage can be bought. Only difference is you get a set amount of points per match (more for winning) and those points are spent on the characters and runes.
