Well the reason of this post is I am somewhat bored and annoyed, by common opinion about archr being support in light armor. I tried to find from where it begun, and i think the main reason is the Thief game. A game in which you used bow to do everything except kiling things.But even earlier in DnD games archery was tuned down in sake of balance ( its not very heroic to kill everything you throw at players before it even can see them). To offset that 'nerf' archery classes were usually bounded with some other 'useful' skills, like thieves, bards, and stuff. And in thet the classes were usually heavilly dependant on mobility, sneaking and such, which favoured lihgt armor. And for them bow was secodary equipment.
But in FFXIV, we have archer. Person who is dedicated to bow. Not some rouge type from some shoddy alley, but profesional bowman. And thats the difference.
From military point of view there were 2 kinds of archers. Light, which were based on maneuver and speed for hit and run tactics, and regular ones which were armored. Most countries armored archers quite heavily. Looking at Roman legions most archers wore chainmail, most of eastern troops did same ( either ringmail or scale mail) The reason most of archers were lightly armored ws purely cost of full armor. And main diference beore archers inlight and heavy troops were skill and experioence. Most of armored one were highly trained troops, while light were conscript expendables. Training of a good archer was taking long time, and for that investemnt it was worth protecting. But also to the degree. During medival times for a price of a good platemail you could buy a couple of villages. Only the wealthies could afford it, and the one who could wouldnt bother to be archers. They were knights, and their way of fighting was stabing, smashig, charging and stuff. Only exception was Japan, where archery was conisdedred an art, and was widely practiced by samurais, which armored thammselves as hard as they could <_<
The TL'DR point is, that archers were second line troops, and except elite troops it wasnt cost efective to heavily armor them.
However when cost didnt matter, in Seleucid empire there were units of cataphrat archers which were prbably the closest equivalent to a tank that ancient army could get. Similar units were used by parthians and continued through sasanid empire suplied by super heavy cataphrats with lances.
In short summary, in a game only limiting factor should be costs, not some dev-imposed restrictions. And yes, heavy armor should give penalties especialy to mobility, and to some degree to speed at which archer can fire, but if you can affoprd plate, than by all means use it.
The two points that should also need to be looked is 1) price of plate armor in MMO's in general is ridiculously small and 2) archers in FFXIV dont have range. I mean we cant shoot for more than 10 metres anyway, so why bpther shooting? it would be more effective to stab enemies with arrows at this range...
In very very short gamer perception of archer is usually like this
