Team Build: Help! Building a team

I need help with building a team! I have no idea what skills, runes and weapons to equip them with. I am A/D who use a scythe/crit build. I havel imited heroes at my disposal atm. Have barely advance any EotN on this char, and i am at kodonur crossroads in the nightfall campaign. I want to blow through Nightfall, Prophecies and EotN with general ease. These are my heroes:
Koss
Acolyte Jin
Pyre Fierceshot
Tahlkora
Dunkoro
Ogden Stonehealer
Gwen
Zhed Shadowhoof
Vekk
Melonni
Mox

Thanks in advance!

First of all, you don't NEED hero's to play this game. so if your hero's suck stick to henchmen. Henchman in an outpost are designed to work in the area you are in where hero's need time to evolve.

Second of all get Olias (quest is done in prophecy's but you get the quest in nightfall in consolate docks. Questname is all for one and one for justice). The best thing to do is make him a minion master using minion summoning skills and healing skills. Minions are a great meat shield and in a group they do nice damage

Third, you might want to check this website http://www.gwpvx.com/PvX_wiki Although not all skills mentioned there are in your reach atm, you can use the builds to get good idea's for build concepts and also equipment for the hero's.

Also, try to unlock Xandra in the Norn fighting tournament.
Nearly all the hero teams include at least one Rit, and it's even more important since you play physical (splinter weapon will be your friend).

Runes and weapons aren't that important at the beginning. Focus on getting the right skills for your heroes first (look on gwpvx.com).
