Shop is mostly cosmetics, there is also boosts (exp, ap, drop etc...), mounts, pets, instance rollback scrolls and titles. The only thing you can maybe call soft pay to win is the 100% socketing things for manastones (tradeable so you can buy it from people with kinah if you need them and dont wanna spend $$$) but that's hardly a big bad thing comparing it to official server and some private servers that sell temperings/serums and other game breaking stuff directly and also doing direct pay to win events, none of that here for now.
So I say it is really worth if you like this version, population recently had a big increase so that's a good thing.
