[PvK]

Sounds like maybe the battlefield orders are the problem. Against indies, you should be able to win if you set up your army so your main body peppers the enemy with slings and javelins and then only has to fight for zero-to-two turns before the enemy routs because Fiends of Darkness and Eagle Warriors (on Hold and Attack Rearmost) have flown over and hit them and/or their leaders in the rear, causing panic and rout. The priest who leads the demons into battle and blesses the eagle warriors can also cast a juicy blood spell or two to help with tougher indies. Summon Imp on turn 3 is a well-timed accompanyment to the above, for instance.
