Complex math
Click for boring math
My first thought is Gold is more stable than Platinum and Platinum more stable than Diamond because of how Elo’s math interacts with color stacking, Hero XP generation and and summons RNG.
Summons RNG limits available heroes ( see Gravemaker, Zeline and Guinevere).
Hero XP generation limits 5* rosters.
Except for the attack stat soft cap, color stacking is only limited by 4* / 5* heroes you can level and Devs have added to the game. See how my wife broke raiding.
Elo’s math is very stable in the MIDDLE, but less stable at both ends. Since much of the math deals with normal curves, the end cases like Diamond are at the end of that curve. Especially individual 24 hours since Elo also assumes a bell curve for each win/ loss/ tie while admitting it is not a realistic model at Diamond or low Bronze.
A good mathematician could customize the trophies but it would have to be rebalanced for each new feature and basic Elo assumptions work well enough.
Players do not understand that with MMOs defense teams are more like partial raid shields than trophy generators. See World’s Deadliest Spelling Bee. Probably should have lead with this.
Rerolls
Since Empires trophies are more about partial raid shield on defense, intimidation is your best characteristic.
We discovered in war that weaker war defense teams work better than stronger if the opponent AVOIDS “wasting” energy attacking them.
Any defense can be overcome, especially with two rematches, but the attacker has to chose to engage.
Simple special skills, heroes with reputations, 5*+1 are all very intimidating even if the team itself sucks on defense and has little synergy.
Try to build a defense team that scares away attackers.
Where is your fun
Hero XP is very limited.
Is it worth it to spend creating a better raid shield?
Often this will require using lots of Hero XP on defense heavy heroes ( looking at you Kashhrek). Perhaps “skins” will help with this problem.
Or to create a better raiding roster to open Wanted Hero Mission Chests in Diamond?
Often this requires little additional Hero XP since attacking heroes for raiding are often useful against waves with multiple bosses, challenge events, and Tourney.
But it’s GLOWING
You can fill a Wanted Hero Mission Chest and leave it unopened until you are in Diamond. Just because it is full, does not mean you have to open it.
Especially with twenty Tourney energy per week, this is often the least expensive option.

Color coordinated centers
You can color coordinate centers by hero star.
Example
3*= Belith, Tyrum, etc.
4*= Rigard, Kashhrek, Boldtusk, etc.
5*= Vivica, Delilah, Gravemaker, etc.
So each player coordinates by best hero. Maybe 5* yellow, 4* Red, 3* purple depending what your alliance has leveled or wants to level. Just pick one color for center starting at 5* defense and going down to 3* ( or 1* defense for newbie alliances).
This works because primarily attacks tend to be auto matched or manually match based on displayed team power.
Example
3* centers tend to get attacked more by enemies with 3* attackers. So if all you 3* centers are purple, they will run out of 3* yellow attackers.
Same for 4* red defenders and 4* blue attackers.
This is the weakness of color stacking on offense.
