Disclaimer: Not all of the encounters found on Warmane are up to par with what would be experienced on retail servers, of even other private servers. Guides will be posted regardless of their intended target audience (private/retail) solely based on their integrity on Warmane itself. An addendum will be added below guides that are best suited for the encounter if they require alternative methods to better suite our server.
I cite TankSpot guides as my primary source.
You should always follow PROPER tactics. If they do not apply to Warmane, deviate as necessary.
Most encounters are the same for all encounter modes, 10/25 heroic and normal. The general difference is increased add/damage/health/abilitiy frequency. Most heroic abilities do not work.
Tactics: Generally on Warmane, the tanks position themselves to the right upon entrance of the room. Same idea just different positioning. Ranged should switch to spikes, all should avoid flames. Do not position yourself to end up in front of Marrowgar as he ends Bonestorm, his cleave is a serious threat when one or both healers are spiked at a bad time.
(These tactics are the same for 10 heroic, 25 normal and 25 heroic. The only difference is frequency of Bone-Spike Graveyard, Bonestorm and the amount of damage the boss does. On heroic versions you have a maximum of three seconds to move from Coldflame without HoT's. Heroic versions tend to cause spikes within coldflame, a major hazard for all players.
Tactics: Lady Deathwhisper will cast a mana shield upon herself upon engaging. In order to begin the boss encounter you must fully deplete her shield via damage while surviving the waves of adds from the left and right. The number of waves is dependent upon how much damage is being put onto her shield. There will always be one wave. Lady will periodically cast a shadowbolt spell causing damage, increasing with the encounter's difficulty. She will drop a death and decay periodically, as well. She will cast an additional spell on random targets known as Curse of Torpor, this ability will increase GCD on abilities by 15 seconds. Periodically, she will revive one of the adds that has been killed, Creating a Reanimated Adherent or Reanimated Fanatic. In her second phase the adds no longer spawn and she must be kited to avoid Dead and Decay. Touch of Insignificance will be cast on the primary threat target, reducing threat by 20% per stack. Finally, Vengeful Shades will be summoned periodically during phase 2 targeting and following a raid members, upon impact they will explode in a wide range AoE.
Heroic: More adds, faster casting speeds. Periodic mind-control on random raid members (25 man normal, as well). Phase 2: Adds will continue to spawn through the remainder of her encounter and must be handled promptly.
Adds: Cult Adherent, Cult Fanatics.
Adherent: Spell caster type that are 99% resistant to spell damage when reanimated.
Fanatics: Melee type that are 99% resistant to melee damage when reanimated.
Dark Transformation - Causes the caster to do 100% more damage.

Reanimated Fanatics: Able to use a self buff called Vampiric Might, +25% damage dealt, heals for 300% of damage dealt.
