Don't nerf archers.
There's just a huge influx of archers due to various reasons, such as people countering whatever class is mostly represented at any current moment.
Plus for example players making STF's of random classes, one week it's a hundred more archers, next week cav, then crossbowers, bla. Everything changes around a lot.
The class it self is pretty much balanced, or at least very close. Jump-shooting can be debated
That said, IMO:Buff the use of shields (Speed & Durability).
Buff damage very slightly on a majority of 1hand weapons (don't touch the speed).
