Yeah I agree that units must be able to destroy buildings much faster than they currently do, buildings are probably OP right now, however this will all be fixed when we begin working on the combat system. Ideally the helepolis will be built closer to the intended target. What could happen is an undeployed helepolis cart is produced at the fort - this can then be deployed closer to the target. Anyway, we have plans for all of this, just need time to actually make it work.
