A way to limit the rgn

Here is an idea to fix the rgn, rather then forcing people to get the same champs over and over instead do an upgrade system, how it would work is combining a champ with the same type as another would provide an upgrade to said champ, so no more of having to get 9 copies of one champ to upgrade them (yes, you need 9 copies to get a 3 star...let that sink in, now tell me, will you ever actually see a 3 star above green?)

A grey or tier 1 would provide 1 upgrade point a champ, In Ex. could provide points to Knight or Noble units and would need 2 and 3 points respectively to reach 2 star and 3 star A green or tier 2 would provide 2 upgrade points to a champ, In Ex. could provide points to Gunslinger or Noble units and would need 3 and 5 points respectively to reach 2 and 3 star A blue or tier 3 would provide 3 upgrade points to a champ, In Ex. could provide points to Demon or Sorcerer units and would need 4 and 7 points respectively to reach 2 star and 3 star A purple or tier 4 would provide 4 upgrade points to a champ, In Ex. could provide points to Dragon or Sorcerer units and would need 5 and 9 points respectively to reach 2 star and 3 star A Golden or tier 5 would provide 5 upgrade points to a champ, In Ex. could provide points to Imperial, Shapeshifter or Demon units and would need 6 and 11 points respectively to reach 2 star and 3 star

Upgrade points would reset upon upgrade, meaning it still would take a bit to upgrade characters

Now while some people are going to look at this and say, what the fuck, this makes it too easy to upgrade characters....but tbh, this at least makes it feel like your actually able to upgrade that awesome 4 star unit, rather then them kinda just being there to fulfill you type advantage (let's be honest here, I have never gotten 2 stars on anything above blue)

As for items....im not entirely sure how we could fix them, other then just garuntee an item drop from npc units every time (Minions, raptors, krugs, dragon etc.)
