Problem: Rakaan siege weapons require 4*3, rakaan xbos 4*4 and rakaan frontline 3*6.
The field is only 10 rows deep. This means Rakaan can not use catapults + frontline + their best range unit to siege efficiently.
This results in my account sieging guard towers as human without losses and 200 power weaker guardtowers as rakaan getting 100% whiped.
I suggest either changing rakaan siege to 3*4 instead of 4*3 (would require a new model), changing xbows to 3*5 or 3*3 with less groupsize (would weaken their active though) or simply reducing dmg and size of rakaan siege by 50% to 3*2 to keep the current model in smaller.
Another option might be to add rocketlike walldamage to any ranged troup but that would simply nullify the usefulness of catapults.
