TBH also I spend six year for Shooting sport irl.
And yes, FW-190 (A4, A6, A8) was my main plane in Il-2. With TrackIr, CH Fighterstick, CH pro pedal and CH pro throttle you can be deadly. I was really proud with my 25-28% accuracy.
I miss my TrackIr in Warband. Pity, I cant use it here. I heard cmp playing warband with X-52. I know - he is cheater:).
There NO wind effects on bullets in Cliffs of Dover atm. There is POSSIBILITY to make it work in future. with Windows 10, 64GB of RAM and 9000Mhz processors.
But back to topic, You dont need a compass to show wind direction. maybe archers could get some stick with strapes/flag on it to show how wind is blowing.
It's more complicated. There too many different factors for trajectory calculation. Gliding arrows, contrary wind, weight of the projectile, shape of projectile, wind direction, wind force, initial velocity of projectile etc... In short - ballistics.
Please - give us Strategus first:)
