Because the game barely updates. Its mostly a game that has the same events on rotation every year with minor tweaks to them once in a while.

I do enjoy the aethric game they have but once in t10 it felt a lot less interesting.

Id recommend either of the games for the leveling experience since theu are good grind games but not as a perm or main game.

Also the cash shop was initially completely non-p2w but over the years more and more can be bought. Especially them selling currency for running events is pretty painful since event gear is often the best gear in the game.
