Based on feedback and some of my own observations, Skirmisher needs work! It is functional, yes, but it is not where I want it / envisioned it to be in terms of play style. For the next major iteration of the class there are already a few things that I want to change which did not make it into the initial release.
Pace Yourself
This was never meant to interact with Fatigue, it was meant to be a flat discount on Stamina costs that operated independently of the Fatigue system. This is important because Skirmishers were meant to use light armor! That makes a Fatigue discount useless. Next point...
Acrobatics
Should not function in heavy / massive armours, period.
Buckler Expertise / Mastery
A bit of oversight on my part, I should have realized a skill that only gave melee block chance was not going to be that useful as you're Vaulting and Rolling away from anything near you. In the future, this block chance should be unified into a single skill, with the other getting new functionality. Feel free to suggest what that should be

Leather Armor Mastery
Something that has been whispered about amongst the devs, we all think this is something that should exist if nothing else for Marauders. Rogues in general should all get access to this skill, and the main benefit provided is instead of lots of extra armor and hardiness, bonus movement speed while wearing Leather. Sounds great for Skirmisher! This would be added to Technique / Combat Generic tree.
Heavy Slinger / Bombardment
A new tree that was meant to be included in the initial release, I wanted there to be a AoE specialist tree that focused on fire and concussive bombs that you were able to sling. I still think this is something that should be worked in, despite DarkGod saying they can't have "grenades". I need to approach him about this again soon, because lack of AoE is something people have commented makes Skirmisher a little tedious to play at times.
BUGS!!!
At the moment, Bash and Smash has the unintended effect of consuming 2 turns when used. This is being fixed asap but I do not know when the patch for it will go live on Steam / etc... Please bring up any other bugs you've noticed in the live game and I will add them to this list. Be sure to bug report them as well in the appropriate forum!
