Many time I lost half health on my main by "toe" shot.
I doubt there were archers with 50+ arrows. Something between 20-30 will be more appropriate.
Btw. Weren't longbow arrows longer and and heavier than standard arrows.
These statistics were from Agincourt.(Juliet Barker's Agincourt: Henry V and the Battle That Made England (2006), ISBN 0-316-01503-2)
A Welsh or English military archer during the 14th and 15th Century was expected to shoot at least ten 'aimed shots' per minute. An experienced military longbowman was expected to shoot twenty aimed shots per minute. A typical military longbow archer would be provided with between 60 and 72 arrows at the time of battle, which would last the archer from three to six minutes, at full rate of fire. Young boys were often employed to run additional arrows to longbow archers while in their positions on the battlefield.
Always go with historical fact checking over "gut feelings"
