Kazper: I get prioritizing the ranged attack/range skill. It can certainly depend on circumstances, whether pathfinding is better (lots of swamps/hills/forests - or is it plains - as well as what enemies are around. But the armorpiercing one is just not that good in most cases. It's highly situational whether you can use the precise shot and the extra ammo are rarely needed (although if it is, you really miss it), but it just never does much for me.
Whereas pathfinding is important both for the mobility on the worldmap, and very important for the tactical battles as well by letting your troops move in any terrain at 1 move and no stamina (particularly no stamina!), if you don't have a ton of plains all around....
Well it also depends on play style. You see I do not often use Barb or other fast units at all. I always use Swordies, Healers, Guardsmen, Monk and Gryphon so they rarely benefit from the Pathfinding skills that much as I have them as a defensive formation for greatest survivability.
As for the Accurate Shot skill, A few levels in this is really good for when one of the guys ducks into a forest OR has say around 4 Ranged Defense it helps you do max damage so you don't have to waste 2 shots on the guy.
Scouting skill is good for 2 reasons. The obvious being the % cleared if you don't find a site. The second and actually more useful skill is the Sabotage it lets you do either with poisoning or false alarm to lower enemy stamina which is quite good.
The Initiative Scout skill is good for a few reasons. For one thing it increases your Ranged Defense, RESISTANCE and Initiative all at same time. Also in regards to having to place first well you should be placing for best benefit for you not so much against or in regards to how the comp places, and getting the first shot off before enemy spell casters or ranged units get their shots off is just to good to pass up.
When you compare the Initiative skills of the Scout to the Wizard you see how good it really is. I mean Wiz only ups that stupid wand firing really which is not that useful until your out of spells and then you have to rest up your stamina to make sure your doing better damage because of Stamina loss.
