ICC - Lich King

[Undergarun]

1. Quake http://www.wowhead.com/spell=72262 - Should destroy the platform by parts, not the whole platform.
2. Defile http://www.wowhead.com/spell=72762 - IMHO area grows too fast.
3. Harvest Soul http://www.wowhead.com/spell=68980 - Should teleport player into Frostmourne and not to other phase.
4. Val'kyr Shadowguard http://www.wowhead.com/npc=36609 - Behaviour not working fine.
5. Life Siphon http://www.wowhead.com/spell=73488 - Spell should have a Diminishing returns that is not working.
6. After one day, teleporter to LK is being disabled without reason. T.T. Same behaviour on server crash.
7. Necrotic Plague http://www.wowhead.com/spell=70337 not working.
