I played Wildstar until I hit the endgame, then hit a massive wall. Nothing new in that, have hit a few MMO endgame walls in my time, but Wildstar has a biggun
Levelling is hugely fun and the combat system is great. Loved my Chua Engineer. But once you hit level cap, everything is gated, everything is designed to slow you down, everything is geared towards hardcore progression raiding and there's some truly enormous time and gold sinks. Probably great if old school attunement grinds, reputation grinds and re-running the same dungeon 100x to get a certain drop is what you want from a MMO, but for me the endgame felt like stepping into a time machine. MMOs have moved on, for good or for bad, but WS seems to be stubbornly stuck in the past. To be fair, this is a deliberate design decision and they haven't tried to hide it. But it's not for me and if the subscription numbers are anything to go by it's not for many.
Since you can buy subscription time with in-game currency (CREDD) I could actually play for 3 or 4 months for 'free'. But I'm just not motivated enough to even do that, even though if I don't use my CREDDs within the next month or two I'll lose them. Which speaks volumes really.
