I'm surprised at the number of people that don't bother with Trailblazer II. I find that there is always plenty of Desert/Snow to explore and moving through it quicker means I get it done faster. I hardly ever take Survivalism with my initial scout because I plan on just avoiding danger and the extra movement from Trailblazer I/II allows me to do that just fine. My first scout is almost always Trailblazer I, II, then movement/sight. The only exception would be if my scout gets stuck somewhere and needs to tank for a bit to survive. As for the +exp promotions that unlock later, I agree that they are mostly inconsequential. If the scout unit is promoted enough to unlock them then at that point it already has all the promotions I want anyway. As a side note, the AI LOVES to drop paratroopers all over its enemies lands and pillage like crazy. It's a tactic the AI does really well, and they even seem smart enough to specifically target important strategic resources. I often don't do the same because I usually assume I'm going to take the lands that I'm pillaging, which means I'll be the one having to repair the damage (not to mention, missing out on healing my front line units when THEY do the pillaging if needed) but I like that the AI does this so well.
