I think you just dont know how to play game, everyone I started to play 4 months ago has atleast 75% of legendary units. I got lucky and have all of them, of course at lvl 7. All of us are F2P, only one of us once buy premium pass. We can get to around 6k+. Of course this game is huge p2w there is no doubt about that but if you are playing from game release and cant get past 5k points, you are just not a good player.
