The relation of the force between the creatures of the game and its history is not correct, for example:
1.- Sight of Surrender: Its a regular mobs.
Hit points: 28.000
2.- Orshabaal: Its a boss and Demon Lord.
Hit points: 20.500
Damage: 3.750 / 5.000 (With 4 summmons Demons)
With the passage of time the regular creatures become stronger, to be a challenge before the high level players.
I think all this old bosses deserve a BUFF, deserve have the same power on lore than in game, deserve be a challenge.
