Advice on choosing units and Morale bug

[Nihilius]

Well, im bored of my first walkthough with CW, my game wasnt very good, shops didnt sell worthy things and the only full set i managed to find was the techno-whatever for dwarves wich i used with engineers and droids, a very overpowered combination i must say, i could do lethal enemies with ease with them, but quickly got bored, so i started a new run, kitted my way to shetterra
and by day 2 i was level 14, destroying everything with the dragon eggs i picked up in the islands.

but im not very creative at choosing units, i want something that is very fun to play with.

i usually go, tank, archmages, some reviving units, and a damage dealer, except the droid build wich was enginners, repair droids, guard droids, archmages, and royal snakes.

i want this time go heavy, an army capable of crippling the enemy really fast, im a warrior so, i dont wanna relly much on ranged units though.

i thought about dryads and fairyes, goblins, and orcs, cant make my mind, and i dont have much gold to try different setups.
for tanks, red dragons, trolls or...?
so what would be your recomendation?

and about the morale bug, well it happens to be most annoying, for example at the begining, when you have the portrat of a knight and human units, you equip the portrat but when you change the unit position to another position where a neutral morale troop was, the human morale changes as well to to neutral, and when you put it back to its initial position the morale rises again, but even unequipping it and changing units, and triying to fix it wont work, so , whats up with that?
