I've been playing for awhile, not as a hard player, but casual playing. And after coming back from a year I think, it has been very different, because it gets harder to get ahead, while OG players can casually make legendaries. Can it no longer be pay to win, or make other campaigns or special events that make it easier to rank up. Portals like the independence day thing is only one campaign, but make it so that it is another world to explore, and get more tokens for new players. I have a lot of stuff, but it is hard to get after doing so much grinding.
P.S
I have a link for people who want to play it on PC, without flash. I think it also has battle dawn.
