Darkest dungeon is a rogue like game where everyone as one specific class and D:OS an kind of open world adventure game RPG with no class restrictions. I think comparing them is like comparing an apple with a strawberry? D:OS has mostly distinctive skill trees, one exception probably would be Phoenix Dive, wich really should be a fire skill. Every thing in Warfare is about physical close combat, but Phoenix Dive is fire related, it totally not fits into Warfare in my opinion.

I guess my main problem with source is: all those skills were source free in D:OS1, why do they now cost source? Did mages become so much less capable since D:OS1?
