Thinking through things (and reviewing the replays)
* The priority of Technical should go up as more features are added that use it. That said, at the current stage of development it does seem that Medical/basic is worth more than Technical/basic; unlike Fitness, the speed bonus from Technical doesn't help much in normal combat.
* The difference in effectiveness between Sidearms/advanced and Sidearms/expert is disproportionate, compared to the other two weapon skills. This is visible for both the Colt .44 and the M4A3. This may be balanced out by the possibility to get multiple kills in one attack for the heavy weapons, and the combat shotgun.
