( Even at equal fighting power, quality is what matters...
And even though my dragon knights are awesome, level 20 will always win over level 10 !
You know, i think that a very good strategy may be to simply stay in your corner of the map, and build a super powerful army by attacking, then letting the enemy gain back the land, let it build itself back up, attack again...
In other words, farm experience may be key here.
Once your 8x8 army is full of level 30ies, then you can start to expand, but not before it feels...
Keeping the trainers behind may also be a bad idea, since they are limiting how much you can train units...
Maybe make them fight up to level 30, THEN get them in the back ?
Mmmh, yes, i overextend myself too much, too quickly.
Time is also on my side since the computer is perfectly capable of keeping itself in check.
I could also, while build myself up, hire any commander that comes my way, and kill them on purpose if they are not useful, to deny them to the enemy...
Still, i maintain my position : Lunatic mode is the easiest mode due to commander death !! )
