I’m too new to really say, but I read ALOT and I have a LOT of heroes and based on my roster I feel like I may never get to fully level:
Kellie/Colen/Gormek - As for Kellie I like Scarlett better as one of thee few fast mana who’s not does splash damage, plus that less attack for 6 turns is amazing, and I have Marjana. I also have other Snipers like Caedmon/Sonya. as for Gormek I already have Grim maxed and Tiburtus leveled so I see no use for him right now, Colen is just too slow mana. I also have Elena and Azlar who would fit better than Colen. And I’m trying to get to leveling Ares, and lastly I also have Mitsuko and BT so there’s that. Sumitomo also has me feeling like he will never go past 3/60.
Kashhrek/Skittleskull/LittleJohn - I have all the other healers with better buffs so Kash gets no play, and the others are just too slow for me
Boril/Agwe/Thorne/Richard/Rumplestilskin - Richard is just a 5 star Grim to me, since I’ve already maxed him I rather go ahead and finish off Isarnia, Rumplestilskin is annoying his special never does what you need it to at that moment always going healing when I need attack or something else. Thorne is boring to me, I use Cyprian and he’s already maxed I don’t need two riposte unless I’m stacking against red (I may consider at a later time, and Agwe eh lol…I have Triton and Misandra. Who I feel would be better than those I listed.
Chao and Hu Tao May never see the light of day - I have Joon/Jackal/Drake Fong/Vivica/Ranvir/Wu Kong and a maxed Li Xiu, I think that says it all.
Ameonna gives people a chance to ghost tile while she’s activate them kill her when she comes back, ha! Obakan I’m just not feeling his simplicity as a 5 star I have too many GREAT heroes especially in the dark category for that, and Domitia because I have Seshat and Sartana who think I are better for my okay style, and I have Kageburado. I may level Bosswolf because he is a huge tank so I can see him being good in a purple mono, but that’s a huge maybe because unless I’m using purple mono I have other tanks with better specials, and BW’s mana is terrible. To top this all off I have PROTEUS he gets all the glory!
