This game has legs, has potential for sure. But, and its a BIG but, when you have to play it online leaving your computer on for hours/days to get materials in order to upgrade your gear its just very, very silly and dumb. Most games of a similar genre have offline gains for exactly this reason. People shouldn't need to actively play an IDLE game 24/7 for days on end to simply get materials to upgrade their gear. 

The quests and general "growth" mechanics are rough atm. They require endless hours of play to accomplish, but literally none of the gameplay is played. You just afk on a certain screen for a day or twelve and call it progression. If you don't want to add offline gains (imo this game is in DIRE need of) there needs to be an active component to compensate. Something to do while actively playing the game that gives rewards, bonus xp, higher chance of material drops, etc. 

And in general, the amount of materials needed to craft/upgrade items are just insane. Like literally insane. You could (and should) cut the costs by a factor of 10 or 20 and they'd STILL be quite high and very time consuming. Its why I personally stopped playing weeks ago, once I saw the epic armor requirements and the time it took to get even 1 epic upgrade item, it was instantly off-putting. I realized I'd have to leave my computer on with this game alone for days and days to upgrade a few items, max. Again --- Its absolutely insane, and likely why the game is dropping off. 

Edit: I just read about transcending and apparently its awesome? But I gave up at ascension 13 cuz again... It slows to a crawl and takes hours and hours and hours of online/active play to ascend at all times. Maybe once you transcend the game picks up, but it shouldn't take you that long to get to the point where the game "picks up". Imagine a AAA game that requires playing for 100+ hours before it "picks up" and the entire world would hard pass on it.
