Talent; Earthern Power - Does not work at all, supposed to make Earthbind Totem remove snares form party members, but does not - Remember that snares are also slow effects, like Mage's Slow

Talent; Static Shock - This one is supposed to hit the opponent with the Lightning Shields when struck, instead it hits yourself, otherwise it works fine

Talent/Spell; Thunderstorm - This one works as intended, only does it have an annoying delay. I am not sure if it is lag or a bug, but it sure is annoying to get hit 3 more times after u use it on a melee

Talent/Spell; Feral Spirit - They actually show! Kudos for that, but they don't attack, nor do you get the related spells and abilities you should have when summoned - This could be a hard script to fix, but it sure would be nice to get them fixed

Spell; Stoneclaw Totem - This one does indeed stun the opponent when hit, but that's all. It does not have 2430 hp as intended but only 1, and nor does it absorb damage from other Totems - You may want to look at the talent Earth's Grasp at the same time, as I haven't been able to test if it works due to the bug

Spell; Sentry Totem - This one does not work, nor have I ever seen it work on a private server due to the complicated script related to this spell - Just posting this to keep you informed in case u'd forget

Spell; Healing Stream Totem - This spell does work, only it heals for a ridiculous amount of health. It is supposed to heal for much more - I am not sure which is the problem: Healing not stackign with spell ranks, or Healing does not get improved based on spell power... Trustable formulars for spell power calculation can be found here in case you need it

Spell; Lava Burst - Wow it works But I am not sure it deals damage as intended. I did some amateur calculations based on the wow mechanisms found on the above link and got the damage result to about 3k higher than it is, you may want to check it again ^^

Spells; Fire Elemental and Earth Elemental - First one does show when u pop the totem, although in a very small version than the intended one, second does not show at all, neither uses any attacks

Glyph; Glyph of Windfury - Supposed to increase the chance Windfury will proc by 2%, but does not show the increased chance at the tooltip - Not sure if it is supposed to show at the tooltip, but I would assume it, and due to the complications to test proc chances I am not even sure if it works or not

Note: I haven't tested Restoration yet, so there may be more to come, good job on the server btw 8]

Edit 1: Alright I have tried some more classes in a few specs, so I can now expand the list a bit

Paladin - Retribution:

Talent; Judgements of the Wise - Does not work at all, very essential for retri pallies...

Talent; Vindication - Doesn't work either

Spell; Seal of Blood - Is not available - I don't know if this is deliberate, but it sure does suck

Paladin - Protection:

Talent; Stoicism - I am not sure about the stun part, but the dispel part is not working

Warlock:

Item; Glyph of Conflagrate - Does not work at all, very important for destro Locks

Talent; Aftermath - Does not proc at all

Spell; Demonic Circle, and Demonic Circle: Teleport - Does not show, nor work, even if you do get the buff linked to the circle - Very essential, fix fast pl0x

Spell; Shadowflame - Does not have it's DoT component, and therefor can't be used with Conflagrate, nor does it make up for the heavy mana cost

Spell; Health Funnel - Heals and damages FAR more than supposed to, like healink 9k per sec - I am not sure which causes this problem, but I think it is set to stack with spell power, which it shouldn't

Edit 2:

Rogue:

Item; Glyph of Slice and Dice - Does not work, and does not show in tooltip

Item; Minor Glyph of Vanish - Doesn't work either

Talent; Lethality - Doesn't work

Spell; Envenom - Does not deal damange, all other effects do work
