Elf (Wing) & Orc (Krag)

Hi everyone! I need your help!!! We started a game a few days ago. Elf (Wing) & Orc (Krag). The map is THREE RIVERS (it's really cool, I recommend it to everyone, big respect to the developers). On this map, you can only play in the late game. The heroes are already level 25-27, but that's not the limit. We'll meet at level 30+. There's a mentor and lots of great items on the map! How should I best develop Wing? Should I take Creature Ability (CA)? Maybe there's something better??? As for the Orc, Krag is overpowered. At the beginning, I can easily lose 6 or more dragons! (He already deals about 3 damage, but he can crit and deal twice as much, + he pushes back on the scale, + he gets reinforcements). As for CA for the Orc, I don't know, my opponent likes machines... As for the items, the Orc definitely has a staff with -20% initiative and a ring with +20% initiative, most likely a Lion set! I'm in a worse position with items: Dragon Eye Ring, Cloak (-luck and spirit), Unicorn Bow, and some other minor items, but I think there's still more to come. There are three of our castles on the map + many additional dwellings of all kinds. I also forgot to mention that both of us have a Pendant of Skill! I would also like you to advise which creatures to upgrade!!! I think like this: 1. Nymphs 2. Dancers of Death 3. Archers with Double Shot (after all, I have a bow) 4. Druids with Channel Energy 5. Light Unicorns 6. Green Ents 7. Prismatic Dragons I want to develop CA + attack with ranged attacks!!! Oh yes, and which creatures should I put in the Blessed list? I think we'll finish this confrontation tomorrow!!! I need advice urgently!!!! Before the end of today.
