My gaming partner and I are looking at tackling the prophecies campaign, (to bone up on the world for GW2) potentially getting the trilogy. We are experienced MMO players, and I am somewhat experienced with GW, but my info is rather outdated, and I don't know the first thing about all the acronyms used by "in the know" players. Please keep this in mind should you choose to respond and help me.

Straight up, we've found that we almost always gravitate, as a duo, into tank and healer modes, just because we know then that "the hard part" is handled by skill we trust. I get mixed messages as to whether or not "the trinity" is in place in GW, and to be frank, if "the trinity" doesn't hold true in GW, it'd be nice to break free from it for once.
My inquiry really boils down to this:
We're less concerned with "playing what we'd rather" if it means we have an easier time in a complex game with a potentially frustrating play experience (as I said, I'm somewhat experienced with GW, and I know how nuanced combat and builds can get), and are wondering what the smoothest "duo composition" is for the direct point a-b of the story. We know that our group will be filled out with henchmen/heroes, and we were wondering what roles are best left for these automated allies.
I'm guessing that she will go primary monk, but my main class depends a lot on what I hear here (and in other inquiries of the same nature that I've heard elsewhere). I could be "the tank" via warrior, but if I can get away with something more ranged and squishy, as I said, I'd enjoy a break from "tanking".
We're not looking to "be challenged" more than need be (meaning we don't want to hinder ourselves by picking "the wrongest build"), we're looking to enjoy ourselves with as smooth a transition as possible. "That build that's just mindless but always wins" is far from a turnoff in this vein.
Thank you for reading and thank you in advance for any and all constructive replies
