I can't decide which I like better to play at the bottom of the chain ladder to finish off chain targets. On one hand the Avian has great attack times that synergises well with non-land attacks such as massacre which is great for finishing off chains. Their attack time also provides them with some form of ambush protection. Coupled with Merch gives them good sustain esp if they bank some credits alongside.
Dwarf Cleric on the other hand offers great NW control too I think. Their MA can frustrate some enemy spells esp if you are active during wave times. Access to horses and 6/3 elites provide good offense compared to avians. Their QF allows them to be fast and coupled with rax can potentially allow your army to return slightly faster than say an undead tact. You won't be able to make as many non-land attacks esp if you end up constantly trading acres with chained undead provinces. Free build also gives you some form of sustain in the event that you end of trading acres back and forth.
They both have great benefits and I can't decide which is better for NW range control to finish off chained targets so they stop posing a risk to your higher up provinces.
Any thoughts?
