If you play pvp for fun, it won't last long, the kits are rather simple and the excitement of rng based wins or losses wears off quite quickly.
If you play to climb and get better, it's not meant to be fun, ranked in any competitive pvp game is about getting serious and going tryhard, it doesn't really matter if the game is balanced, you play to overcome the challenge.
personally? I'm trying to hit crystal, I am poopsocking dragoon and since this is solo queue only there is no social interaction to be had, this is a lone endeavor that feels a lot like work, but since I'm obsessed with it, I just soldier on
fun will come later once I can afford to try out new classes and actually learn the game, for now all I need to do is keep playing more and more games until I make it.
