llo Kakashi,
All the time will be a little bit over reaction but to be honest it's not a game which you will play for more than 1 year.and most of the players are giving up before lvl 60.i"m playing for 1.5 years.i this time I manage to finish all dungeons levels and make around 60M dmg on UNM CB and gold 4 arena all the time.
I will tell you what are the biggest problems in my opinion.
1)for getting a legendary champion you need to spend allot of money and after maybe you will get a duplicate.
2)farming good gear is taking very long time and energy which offcourse you need to buy it.
3)we don't have where to farm books for upgrading the champions skills.
4)we don't have where to farm silver and silver you need for literary everything.
5)a low spender (50€)/month don't have any chance to get in platinum arena because the platinum places are decided in the last hour and is all about how many arena tokens you will buy.
6)you need to play minimum 4h/day to be able to progress on this game. Don't have any possibility to make it faster or instant and it's not because will affect the graphics, it's about that the people will not spend such more money to get does champions which will help you farming more faster.
I think I will stop here because are allot of bad things to say about this game and the only good thing what I can say about this game is there graphics and the game style( synergies between the champions.
