Yes, that I am aware, I cannot change classes on the go. I already went through my pockets and bought a fair number of house runes for this purpose (mind you my character is still very young, across 3 classes the total level is just over 70).
And I did some reading and I am (relatively) happy with my class selection. But perhaps I should reiterate my question.
Let's just say I have an imaginary Talent setup on my Priest (counting both Priest common and priest exclusive) as A, Mage setup B, and Knight setup C.
Is it possible to have a setup of A, B and C that I can DPS with say BA, Tank with CA and heal with AC? IE is it possible to switch roles by switching classes and gear, and not having to go near resetting talent setup at any time?
If I'm understanding the question right, you want to know if for example you are playing your M/P, and want to use your K/P setup, can you? If that's the question, then no, respectively if you are a M/P at that time, you only have access to your mages primary, elite and shared skills, as well as your priests shared skills (like regen, urgent heal). Your Knight skills are not accessible at all till you swap to either K/P, P/K, M/K or K/M.
Didn't see vfwiffos' post when I posted mine lol, but essentially what he said as well.
edit #2) You do get a talent reset stone in your level up gift bag (at what levels, and how many you get, I don't remember) at some point. If you have diamonds to spare, then that would be the fastest way. If you have tokens to spare and no diamonds, then it's probably time vs money here. (Time being spent on obtaining tokens, money being spent on diamonds).. or option #3 would be buying it from another player (pay them for diamonds to gift you the reset stone).
annnd edit #3! If it was me, I'd probably be using tokens truthfully, as diamonds aren't so easy to come by these days with skint pockets lol, I can't speak for others though
