So, I have thought of this idea which I know will not be taken into consideration. So here's it, as u r going to release the new system, it will be really very tough to progress. for suppose u r on tier 2 and want to go to tier 3 u will have to buy the stuff in it and then rank upgrades it unless u have the necessary no. of stars, and once u finally reach it u will have to repeat the same process again to go higher. when u finally reach the tier in which u have the stuff u wanted, u will again have to need a huge lump of money for it. 

So, why not just have rank upgrades of stuff that costs coins and no system of level upgrades? And when u finally reach what u want buy it for credits. This will simplify things a lot and even make it easier for f2p guys to play. Or else people die till they reach the last tier. coz, if u r keeping it like upgrade things of every tier (that u don't even use) just to reach the next one and again save money for stuff u want. Wouldn't that be annoying???

I know that devs r hungry for money$$$ but can't they do this much for the players??? Also, XP was something that u could get after battling and completing objectives. but bcoz of this system, p2w players can get all the stuff within a few seconds.

What say, guys, pls let me know about this idea.
