Hello, welcome to forum.
You have good rosters.
I will suggest you leveling up rainbow color, so each color 1 heroes.
And I suggest you also leveling *3 heroes. You need stacking color and also class trial quest, and it will help your progress, because *3 heroes is fast to level other then *4 and *5.
You already lack of mats for *5, so Anzogh, King Arthur and Joon sit at 2.60. And also Richard 1.50, Obakan 2.36. They also will lack of mats. And basic stats *4 heroes 3.60 is better then *5 heroes at 2.60.
Do not focus on them yet. Just focus your *4 and *3 heroes. This game is design for long-term play.
For defense based on your rosters level.
Arthur - Anzogh - Cyprian - Joon - Obakan
For attack in raid/war/quest, best is level as many good heroes, then we can have many option to choose based on the oppenent.
Bring all good *4 heroes to 3.60. In order priority from left to right.
Red: Boldtusk, Sumitomo, Keleli
Blue: Kiril, Sonya, Boril
Green: Kashrek or Little John (both can make as your tank candidate)
Yellow: Wu Kong (good for titan and raid), Danzaburo
Purple: Proteus (best), finish Cyprian to 3.60.
Consider for keep *3 heroes:
Red: Rudolph, Squire Wabbit, Namahage, Hawkmoon, Nashgar, Azar
Blue: Gato, Valen, Ulmer, Gunnar
Green: Muggy, Belith, Brienne, Berden, Mnesseus, Hisan
Yellow: Bane, Gan Ju, Melia, Kailani
Purple: Balthazar, Tyrum, Chochin, Gill-Ra
Tips leveling (only my opinion):
- if you get *1 heroes on-color (same color) feed for your *4 heroes which is not yet 8/8 skill, you can 10x at the same times, but if the heroes is stuborn can not up the skill, use 1-5 at a time *1 heroes same color. And after has 8/8, you can feed *2 combine *1 heroes on-color and use 10x at a times.
- if you get *2 heroes on-color (same color) feed for your *3 heroes, use around 1-5x at a times.
So, slowly but with this plan, you have more choice, and feel your playstyle which is better to ascend and so on, or later you can ask in forum again.
Good luck.
