I fiddled around with 18 pop, though that already involved heavy deer pushing.
Since they don’t have an eco bonus in dark age, I think 17 pop is hardly possible to reliably pull off.
It’d depend too much on the fact when you spot your deer and how far it is.
In most matchups, I wouldn’t play that though. 20pop milita/maa into range is much stronger imho.
It fits their bonuses much more with stronger skirms in case the opponent opens range and it sets you up better for Castle Age where you are reliant on xbows.
Also opening scouts against another scout opening will put you behind (at decent ELO, maybe 1500/1600+) because the opponent won’t fight you until he has better upgrades (- at lower ELO this might work).
Scout -> archer is possible with ~20:30 uptime (if you delay fletching) , but you won’t have a huge mass of xbow in that case.
