A little advice now that I have leveled up a few more heroes

Ok I have posted on here a few times with basically the same question, and it’s which line up best suits my defense team, and in what order should I place then. I am in the process of making out Rigard now. But I have quiet a few leveled.current defense team is ,Sonya, Boldtusk, Kash,Kiril and Tibertus.

I’d say that you have too many healers in your defense and it lacks for firepower. Kasshrek is a good healer itself, so no need for flanking it with two more. Second, Tiburtus at a right wing is not very effective as he fires last and other heroes can’t benefit from his defense reduction.
I don’t have Proteus, but as far as I remember he stops mana generation, so I’d include him into a defense.
May be: Proteus - Grimm - Kasshrek - Hu Tao - Kirill or
Proteus - Grimm - Kasshrek- Kirill - Chao

Well I took your advice on a lineup change and I have lost almost 200 cups since, thanks anyway
