the power tree of the Misty Mountains is the one I like the most, however, one of these power could give the player a better feeling if it was enhance a little bit, I want to talk about Eternal Strife.
This power lacks some visible impact in my opinion, my suggestion would be first to reduce the spell cooldown, then to enhance slightly Moria and Goblin-Town effects :
-I liked when Moria goblins had triple poison damage, but that was maybe too strong, instead they get passive poison damage now, but my suggestion woiuld be to increase also damage over time done by poison of all Moria units.
-For Goblin-Town, more resources and desactivation of buildings are good, but in my opinion, it would be original and fun to add the following effect :
"Goblin town tunnel diggers dig their tunnel a lot faster"
This effect would alow tunnel diggers to dig the second entrance almost instantly rather than 7 seconds later, which would enhance one of the funniest and hardest type of gameplay in the entire game !
