I would wish that intune with todays changes that HTC consider hardening Town objects. (by how much I would leave to their judgement)
But at least to bias further agin the use of 20mm's as town object killers.
Hopefully the changes promote attacking positive game play rather than negative porking tactics.
However in order to give a side the time to respond to small> medium undefended attacks on towns it would be beneficial if the time required at target (ie the town) was extended or indeed the size of the attack required to instantly turn a town over be increased from that currently.
