In the FFXIV world, lore-wise which job is the strongest if there was a tourney?

[Mysterysword]

If by easily you mean just barely penetrating the mail and stopping on the padding underneath (medieval English longbow vs medieval plate), or just bouncing straight off, then yes.

No, I mean that it is possible for a longbow archer to kill someone in one shot. The draw weight of an English longbow was at least 80 pounds. That's just based on the physical strength of the archer, not counting whatever magic an FF XIV BRD/ARC may be using to augment their draw, which could easily double it. And 80 pounds is the low end of the estimate.

I'm more curious as to why there seems to have been no history of the crossbow being invented or used in FF XIV, because here on Earth, humans had crossbows in the 6th century BC that could fire with a draw weight of 200 pounds.
