more speed helps if the enemy is not dodging too much. dodging would be a natural and logic countermeasure, but missiles tend to overturn and loose the target. - it would help to give missiles a MUCH longer lifetime and a tracking ability ( line of sight ) of 270 degrees. that way they d become much stronger chasing ships.
if it was possible, - a missile should allways launch with a momentum of zero and accelerate to its maximum speed. that way, we wouldn t get missiles that fly backwards with full reverse thrust ( when E-killed and fired backwards at 200 backwards momentum ) - if missiles used their own speed only, they d turn better and wouldn t easily loose track.
missile ammo using up cargospace instead - and having the max missile ammo at someone very high would be desirable, but calls for a massive balancing. - cargospace is often added without much thought about weapons. - if one for example buffs up missiles some hybrid assault shuttles, like the turranic raider or the armoured transport could become fighterkillers, just cause they CAN carry tons of ammo and have missile slots.
if its only applied to warships though we might have to revise the different sizes of the ships and their cargoload. - a BHG gunship still has too much cargospace compared to a rheinland battleship. 250 cargo is 1/5th of a battleships cargo? - and the gunship isn t even 1/100th the size of a battleship.
