I've noticed that some encounters listed as Deadly or Epic seem to give much less Exp to my same team as those listed as Strong or Medium. For example, my same team leader just seemed to have received 188 exp for clearing a "Strong" earth elemental's squad, but 77 exp for killing the Ashwake, Thingycoil, and One Other Dragon trio in an Epic encounter, while a single Obsidian Golem listed as Deadly gave 94 exp. Not that it matters at that point, but defeating Waerlorga the Dragonlord only gave my team 15 experience...
Is there some sort of bizarre algorithm here I am missing?
