Sorry for the lack of activity again - been a bit busy with some RL stuff.
I've been working on the interactions as well as transformation forms - I got the demon hunters pretty much done - only Night and Blood elves will be able to become DH's - correspondingly, only those civs will have War Glaives available as weapons. All of the transformation forms have most of of the NO_X type tokens, along with having a 1/3 force-halving property similar to geo saurians (with one exception), making them tough to debilitate.
Demon Hunters have 4 abilities - Mana Burn, Netherwalk, Soul Barrier, and Metamorphosis - Mana Burn causes dizziness, pain, and bleeding, Netherwalk is a buff that increases speed and agility, Soul Barrier increases toughness and willpower, and Metamorphosis turns the user into a giant, horned demon which can fly and throw fel bolts as projectiles - basically the WC3 version of the demonform. During that time they have highly increased attributes and learn the sword skill four times as fast.
DH's also do not require eyes to see, and can sense various types of demonic creatures, same way as vampires sense living creatures. They also get a sizable boost to agility and strength.
Paladins got a Turn Undead spell now which removes NOFEAR, NOPAIN and NOEMOTION from a single undead target - some races will also be unable to become paladins, mostly the various undead, demonic, and aberration (i.e faceless ones) types.
Sorcerers now have Skeletons and Skeleton Mages as their undead pets of choice instead of the previous "revenant" type, whereas Biomancers will have Plaguebearers. Druids wont have the treants as "pets" once I get around to revamping them.
I've also done the transformation forms I intend for the 4 Troll priest types to have - I still have to do other spells for them, though. The 4 forms correspond to the priest bosses from the old Zul'Gurub raid - a tiger, a serpent, a spider and a bat.
The tiger form (or Tigon as going by the WoWpedia version) will be a fairly simple yet tough physical attacker - mostly having increased speed than other creatures by default.
The snake form (or Slith) will be slightly more defensive, having a 1/2 force multiplier as opposed to 1/3 - also can inject poison with its bites, and also spit it and acid at enemies.
The bat form (called Blood Seeker) is another flying form - it's bites can suck blood, and it can release sound waves in a similar manner as the banshees, and also scream in order to cause fear.
Lastly, the spider form (called Widowspawn) will have a necrotizing bite and ability to spray webs - its immune to webs itself and is also a stance climber.
I'm not exactly sure what other spells the voodoo priests will have yet - I want to get atleast one of them Hex as a way to transform enemies into toads. We'll see though.
I'm also uncertain as to the druids - I definitely want to make their forms more in-line with WoW, so they'll get a unique bear form, a cat form and a moonkin form, along with some syndrome causing spells and probably a buff of some kind.
Lastly, some combat logs from testing:
