Personally I've been just enjoying the ride with sub-optimal builds and challenging myself.
On one note, adrenaline is scoundrel skill.
Speaking of adrenaline, I liked it more in OS1 EE. Now it's just auto-use since you will get to transfer those AP to next round where as in OS1 it was more situational and you actually had to plan for it, and it was still very good when you managed to finish of one more enemy before he/she/it got to act.
