I must admit I have enjoyed reading the comments on this thread so much that I thought I would add my 2p.
Olias - the freaky dude - is always my MM. he has a few different builds but is always MM
Livia - hot hot hot - is Ne/Rt and does some spirits n stuff. I always bring her and rarely change her build
Master - scary man - is either SS or SV
Zhed(head) - water/earth ele, usually with wards for fire heavy areas
Vekk - he runs funny - Air/Earth ele. Usually air spiker of some sort
Sosuke - (hate his elite stolen armor) - Fire ele, SF mostly
Jora (dang she's big) - Axe
Koss (check my afro ladies) - Sword (usually HB)
Goren, dumb as a hammer - so he gets one for knockdowns
Anton and Zenmai - dont use them much
Dunkoro (heal me you dummy) - aka Dumb Koro
Talkora - a good prot monk
Ogden (old git) - smiter - not used much
Morghan - not used much - Commandagon
Hayda - again not used much - Motigon
Kieran - Got him on a couple of my characters - runs quite well as P/R with volley
Razah - it scares me mommy - Channelling spirits
Xandra - in my party most of the time - Communing spirits
Pyreee - My fave ranger runs with his pet tiger
Magrid - only in when I need her, poison interrupter
Jin - Always seems to get forgotten, rarely used, normally rn splinter barrage
Norgu - Panic mes normally - I mean wouldnt you panic if you saw him coming towards the buffett...
Gwen - Dom mesmer, echo chains etc
MOX, Khamu, Melloni - havent seen much use, but may well change with the new derv updates
Overall, I generally use Livia, Olias and Xandra for most situations. I have H/H most of everything in NM and HM with these guys with few problems.
General AI issues, the lack of a brain to move when a meteor/maelstrom starts, not rezzing when they need to or rezzing when they shouldn't, but generally ok!!
I like my heros and I will miss them in GW2

I use most of the times master/olias/livia with the Discord build. And if I’m in a team that already has discord i bring Gwen with Panic for the interrupts.
The rest of the heroes i don't use so often
