More a thought triggered by your post than a meaningful reply:Only time I've fought a 1 hp minion-11 ogre, our 4e PCs were 2nd level!
Yeah that GM was not the best...
I don't get the idea of running a system that has pretty clear advice on how it's meant to work, and then just ignoring that advice. Is it some sort of "dare" to the designers? Look what I can do that you said I can't!
A 2nd level solo ogre doesn't seem that hard to design:
defences as appropriate for a level 2 brute; 176 hp; threatening reach; ogrish smash (melee 2, +7 vs AC for 2d6+7 and dazed til EnT); ogrish anger: make 2 smashes; ogrish fury: when bloodied, make 3 smashes; minor action, 1x/enc, recharge when bloodied, fearsome glare (1 target in close burst 5, +5 vs Will, -2 to attack and defence (SE)); immediate reaction, if successful on an opportunity attack: fling away, +5 vs Fort, push 3 sq and knock prone).
That thing's not going to die if it gets pushed down a 10' pit!
