Xliest 7 Attack that cannot be upgraded that costs a fortune to upkeep....
EA's are 6 attack so I am trying to see your point of the argument.
Mages are needed for the Elven Special tech. If you take them away or make them hard to upkeep, you might as well change the Elven tech to allow wizards to cast those spells. That would be the only way its viable now.
As for your attack, is that the one that Thane explained how you got "cheeks clapped in the long range and mid range" 😉
You cant compare attacks right now anyways, everyone has inflated armies not having to upkeep anything with unlimited resources. Hell I am running THOUSANDS of war machines, which would be impossible to upkeep if I wasnt being fed by Keepers gifts.
