Archery is fine as it is, there are plenty of foot archers that do very well, the top bows + decent power draw already do enough damage.
If you think it's hard as a Foot Archer you should try playing Horse Archer, it's weak as shit until you get to level 30 and even then you only have a strongbow with 5 PD, it takes me 3+ shots to kill most people from full health and I have to do that whilst riding on a horse.
Infact I'd go as far as to say 4 shots or more hits if they're wearing medium to heavy armour, plus as a foot archer you can also get Power Strike and some melee WPF if you want to. Foot Archer is powerful when in the hands of a skilled user, if you think it's weak, either your build or your skills need improving.
I like it as it is and any kind of buff to archer would destroy the 'balance' we have now, I say 'balance' because obviously it's not 100% balanced, but it feels pretty damn good right now and archery is definately something that doesn't need to be altered to improve that balance.
To sum up, either nerf throwing, or buff arrow speed.
Lol no way, arrow speed is good, if I can hit moving targets whilst moving fast on my horse, sometimes at a considerable range, then I'm sure it's fine for any decent foot archers. Throwing and Archery shouldn't be labeled together just because they're both ranged, Throwing is its own thing and it will probably be toned down.
