Should (certain) artillery have a low arc toggle? (Basically by duplicating its weapon, but changing to the ballistic arc used by direct fire cannons, and giving it a switch like nanodarts have).
Low arcs have several advantages over high arcs--would anyone still use high arcs besides to get over walls or terrain? It would be more noticeable that muzzle velocity in T1 artillery is LESS than in T1 tanks.
