I don’t think I have ever seen those words used in conjunction with warrior before. Healing sure but massive damage? That’s the realm of hunters.
Somnus is fun. More fun that slyphen. It really depends what you want. Somnus has a hard ceiling. Once things get to a certain point and he can’t blow them up he becomes useless. Below that ceiling he will be fairly consistent. But his spells are enjoyable and his play style is more simple.
Slyphen has a higher ceiling due to one shots. He can set up bases somewhat and can clean up very well. But he is substantially harder.
It really depends what is important to you. Fun Or viability. It also depends on if you want a more chill dragon or a slightly more complex one
