What I do to avoid this is keep one unit of arbs or some other unit and they will run out at a different time. This gives my troops missle cover while I swap out my longbowmen. More continuity. If your position takes a charge while you are swapping 4 units, it's like taking a 4 unit handicap, while only swapping 3 at a time is less of a handicap.
Still for missle troops, I'll take upgraded HA type units (IE Slezcky, Boyers, Byz Cav, turkoman hourse, Steepe Heavy Cav ... ) over longbowmen anyday, except when defending high ground. Mobility and the ability to run down your enemies, or intercept reinforcements really give you more options than lonbowmen even though one on one a dedicated missle unit will decimate mounted missle troops in ranged combat.
