Excelsior

can some veteran provide some advice on the tough ranking of the following 10 monsters?
-Balron (Not a Paragon one)
-Yamandon (Not a Paragon one)
- Lurg
- Minotaur (in Babyrith)
- Irk
- The Darkngiht Creeper (Doom)
- Abyssnal Horror (Doom)
- Fresh Renderer (Doom)
- Impaler (Doom)
- Shadow Knight (Doom)

I knew that it is not apple to apple but I want to get a general idea how tough they are

Assume using pets (5 max pets) listing easy to hard:
irk
balron, lurg
doom bosses
Minatour <- i suggest not try to kill nothing worth for your effort
Yamandon (assume that its a valor champ boss, or slaarion itself)

Thansk for your advice.
I do not use pets but solo. My ranking is (easy to hard)
-irk
-lurg (bring him to the entrance, flee when hits point is low ... take some times)
-Balron
-doom bosses
-Yamandon
-Minatour (It is really hard, only one hit and die)
