Runes of Magic US / AU

Been messing around with warlock and I can't figure out how to build Psy points. From the description psychic arrow is supposed to build points correct? I didn't see any buffs I needed to have active or anything else like that so thinking it might be bugged for the moment? Just curious if anyone has had issues with this or I could just be missing something. Info/input appreciated

I kept looking for some sort of buff to appear on right hand side of bar like druid gets when using certain skills lol. Much appreciated

Also, there are more and better skills to increase psi.
Warlock General: Psychic Arrow- 2 sec Cast - generates 1 psi
Warlock Primary: Puzzlement- 2 sec Cast - generates 2 psi
Warlock/Mage lvl 20/20 elite: Flaming Heart Strike - instant cast - generates 3 psi
only problem with Flaming Heart Strike is that it has a 65 second CD : /

And puzzlement has a 25 second cd on it if I recall correctly =/ I'm really interested to know how this will play out considering it takes 6 psi just to enter state of willpower/willpower blade. So far I've been having fun playing it, but I'm just wondering how building psy compared to spamming other skills is going to be more beneficial given the plethora of insta cast skills warlock can keep launching. I think it will make more sense when I'm in an actual boss fight, but just curious to know how its going to stack up against mage dps and is this going to be another token class, which will finally get fixed in a couple of years. Also a question to add to this is how does dark damage figure in? I notice we have a skill that increases "dark damage attributes" least I think that's what its called. I figured something like that would be capped at 50, but again I'm not exactly sure how it figures into over all damage aside from the usual magic damage.

its a bar right under your hp/focus/and whatever 3rd class energy bar is...the bar is broken in to sections to represent each psi point. psi arrows/puzzlement both add psi points. What I'm assuming is that the psi points don't diminsh on boss fights the same way they do on regular mobs. I noticed you lose the psi points when the target dies.
