I’m only up to vanguard, but its pretty obvious to me that its time to stop leveling lineage. First of all, they are nearly all worthless, but mostly its the food. No matter how weak and worthless they are, they all seem to have 40 worthless levels, each requiring two or three food raids. That’s like 100 raids for a dragon I will literally never use.
It is MUCH better to just park divine dragons at different class tiers, and ignore lineage. I could be convinced to level them up in my spare time still, but the food required for each level needs to be reduced, by a lot. Maybe with an 80% reduction in food per level, I could be convinced to level them up past breeding.
