The bar can tell many thing about user. For ex: with bar of Darkstab.
CP, mana, horse and dash on Tab 1. Hide, mirage, UE, exciting adventure tab 2. All is defensive/buff skill, especially with CP, horse, dash in tab 1. I guess he's the kind of assansin hit and run. Bluff and backstab are the only 2 agressif skills on tab 2. I think he will use them while click on those blow on tab 3. If I'm not wrong, he was in Enter-chat mode

.
Usual simulation: Mirage -> hide -> crit wound -> backstab - blows - bluff -> If target run, then shadow step - back stab etc -> Then horse/dash
I'm not really good at dagger so that's all that I can find out

For the bar of Falene : kind of a typical bar of a HE. Atk - CP - stun - Dash - Pots - 3 toggle skill in tab 1. CP is placed before stun. And in tab 2, UE is placed at first place, then snipe(which allow u to hit from the longest distance IG). These 2 skills are placed even before rapidshot. So she tends to start battle from a distance (which allow her optionally to use HE). From those assumptions , I guess that she's kind of defensive archer (I mean not the type that simply rush in, hit and die). Regardless of accuracy, which is a must-use toggle skill, Focus skill mastery is placed before vicious stance; more over, all the buffs blah blah of sagistarious is on the second tab. It shows that she likes to spam stun. One thing that I appriciate from that bar is the assist button(what many ranger don't know). However, I prefer to right click on party .
It was only my idea from your skill bar(maybe totally wrong

). Hope that you 2 are not disturbed.

P/S: Don't imitate me, I'm a nab dagger :<
