Luckily MOBAs are build off player feedback and constant updates, so STS will be updating the game regularly upon release. If the game isn't constantly expanding/changing, playing a single map over and over in pvp will get boring, so adding new champions or giving buffs to nerfs to constantly played/complained about champions will keep the game more fresh in the long run. Vainglory and CoC absolutely need updates and changes to be a success.
