I have been playing, and I mean almost daily, since around the game was launched and have seen lots of discussions about power and rng. I understand this person's frustration, about how so many folks have a flood of amazing champs with amazing abilities, fully ascended and leveled, etc. Everytime someone posts a roster it is mind boggling.
I have none of those, I have been waiting years for champs like gorgo, lilutu, valkyrie and a whole bunch of others many seem to have. I just got Monster recently, but still no big names in show business. I am FTP but that ios not supposed to matter. My "luck" is amazingly bad. All my colored shards just produce low rated champs that are not worth bothering with. I have collected a total of 4 legos, warchief, aleks sharpshooter, cillian, and teela. Not real ones to make ones boots quake.
Most everyone in arena has the free Ninja. I don't, I took time off from the game and missed that window for ninja. Now I face him in practically every battle in arena.
So it is VERY easy to say all you need is this and that and so and so. But this game is very cruel in what you don't get. I know the saying here is take what you have and make the best of it. Well when you do not have L60 and L16 everything like the bigshots it is not so easy.
I used to survive in Gold 4 somehow but things got harder, so staying lately in Silver 4, but trying to get enough medals for Great Hall is nigh impossible. Arbiter is another that many seem to have, it used to be much easier but I missed that also. But I really do not miss arbiter, I still wish I could get the champs by chance that so many others have.
