Chanters get dopples in THJ basically doppelgangers that cast your top 6 gems not sure what level though and its through AA I think. I never played chanter.
rogues are awesome because of backstab in the front, poisons that scale off of spell dmg and have the best skips Sneak/hide shit that no one sees through
Pally have the sheld/1hs buffed to the max, quick heals to keep trio alive
Shaman, well slow/haste/puma buffage up the ass
SK sustains through taps buffed by AA
Bards are awesome in any comp can string together buffs and they just stay on indefinite
Pet cucks, 2-3 pets depending on makeup, when THJ was at peak the combo of choice was Mage/BST/BRD but you can do 3 pet with necro. Mage gets super pet bag with AA at lv51, and along with his Epic makes like the best pet tank ever that heals itself with the proper weapon.
Clerics do well with any melee since their AA and divine aura buffs the shit out of them
Rangers get super bows unlimited ammo and no range penalty, so you can jsut bow shit down while face tanking it, lol. Good combo back int he day was RNG/CLR/ROG
The way progression works is you have to kill certain raid targets in a non respawning instance (hail NPC) and then hail the NPC that shows up after you kill it to complete your flags. There is NPC in Bazaar that tell you what you have to kill for flags. Then you can progress to the next expansion and so on.
