I keep trying different demigods and alternative builds.\
Right now I love Queen of Thorns as a pure general.

When playing multiplayer games the overwhelmingly popular choice seems to be regulus.
This in of itself suggests that he is overpowered.
Multiple regulus together on one team, if they coordinate, are a particularly deadly combination.
Even playing well, its difficult to withstand such intense focus fire.
I played a 6 player game the other day.
EVERY other human player was Regulus.
