It is definitely not without it's issues, even after a long time after release, crashes happen, not as often but nonetheless. After you've reached lvl 30 with all characters, maybe got a couple reds for each, there is very little reason to keep playing, not to mention the excruciatingly low drop rates for red items (best items in the game).

*edit: some of this changed since the Winds of Magic update, you have a whole separate game with competitive elements like the leaderboard, but the biggest problem I have with that is that it is completely separate from the base game, which means you'll have to grind a lot more to upgrade the items in the Weaves...*

So you end up playing the same maps over and over again, relying solely on rng to get easier bosses, fewer hordes/patrols etc AND even after you get all the tomes required to gain an emperors vault (a chest with highest drop rate for reds), it is not guaranteed to get it, in which you have no guarantee to get the red item... pretty annoying in my opinion and remains one of the only major issues I have with the game.

*edit: again, Winds of Magic fixed this issue somewhat, I've been getting much (like A LOT) more reds since the patch and apparently they made it so that you can get reds from all chests in the game, including commendation chests. So in my opinion, the problem has been handled well, after reaching lvl 30 with every character, I managed to get enough vaults and chests to get my favourite red item setup for each of them, something I wasn't able to do before.*

If you are ready to get your ass kicked by some demon vikings and religious rats with crazy magic stones and poison and a horde of goat people barbarians worshipping those same chaos gods, you are in for some of the greatest the genre can offer (sprinkled with some grimdark lore)... A definite recommendation
