I've played it since the beginning of beta and it was good untill they started to update. To be accurate, they changed some characters so much that it changed the game completely and kiled the all fun for me at least. After that I uninstalled the game and few weeks ago I downloaded again, but didn't start it at all. I am too lazy and I really don't believe that game changed on better
The game WAS half decent, but when it takes 30 updates (on a beta) and you still do not have a finished game, well that tells you something about the development process of that game.
I've played it since the closed beta release and it was enjoyable, but as it was stated, they changed certain characters and certain cards so much (not to mention moving them around from common to legendary, back and forth and back and forth ...) that it stopped being enjoyable to play the game.
Last one would be the fact that if there is one thing Blizzard knows how to do is advertise. It has the money for it, and it has the creative team for it. Unlike Blizzard, Hi-Rez barely advertises. Sure you might see some in-app advertising or some banner online, but Blizzard goes all out with TV Ads, Billboards, etc.
Might just be my browsing habits, but I do not remember seeing more than 2 or 3 websites with advertisements for Paladins, and that was before the closed beta started. After that, I haven't seen anything, and right now it just seems like a project that is going to fail.
Constant changing ruined the game! That's the biggest reason why most of the people left the game, including me. It just killed all the fun. Few weeks ago I downloaded the game again, but didn't even started I am too lazy and I think that game is dead for now, if they managed to find formula that will satasfy everyone, I will be back
