Arua combos that should not be!

I think that PoE shouldn't rely much on "ramdomic" type of game, diablo 3 is losing players because of that...
The sollution would be to give better items depending on:
- The type of mob;
- The mob's aura;
- The combination of mob with aura(cause some mobs are more effective with some auras);

I think that would solve the problem of the reward.
And would be a choice of the player to:
- run for his life;
- try getting the mob cause it's almost certain to have a good item, but this way you will put "your life on the line".
- or die trying and get nothing in the end cause you can't beat him yet. XD
(i think the last one would encourage one to play more and get stronger!)

As long as they don't get "stuck" with ramdom too much, the game wil be fine!
