Daikyu bow and Wako Raiders

[Uselessindeed]

Daikyu Samurai what upgrades to add to them to make them cost effective ?
Wako Raiders these units seem great as the above im worried what upgrades to add to them because as u know u cant undo them once you've upgraded them.And want them to also be cost effective.
Any advice or helpmost welcome

I tend to use reload and accuracy and extra ammo, plus range on Daikyu, normally 4 upgrades then range so take your pick on accuracy or reload. With Wako, I just get all standard att/def and then all clan token attack. With 1 standard morale or charge depending on pref.
