When are we going to be ready?

Hi ppl...look! I was just wondering when are we going to be ready to take down this dragon together? I am sure it will be fun ;)

Here are some of his special abilities:

Sleep - Roaming AoE sleep cloud that targets random areas around Lethon and sleeps players caught within for 4 seconds.

Noxious Breath - Deals 3000 Nature damage and applies a 30 second DoT that increases cooldowns on all abilities by 10 seconds and inflicting 350 to 450 Nature damage every 3 seconds. The DoT can stack up to 6 times. The main tank should be the only one affected by this.

Tail Sweep - Knocks anyone near his tail back, inflicting 600 to 1000 damage.

25% ability: Summon Shades - Everyone in range will be stunned briefly and a shade will walk out of their body. The shades will walk toward Lethon and will heal him if they reach him. The shades have 1 health and are immune to AoE spells.

Mark of Nature - If a player is killed by Lethon, they will be afflicted by a 15 minute debuff called Mark of Nature. If resurrected during this time, they will be slept for 2 minutes rather than 4 seconds if they enter combat.

Shadow Bolt Whirl - Fires four sets of shadow bolts at everyone on one side of him, then alternates to the other side, dealing 800-1200 damage. On each volley his feet will glow.

Port - Ports the player who has the most aggro in front of Lethon if he trys to run out of combat. This ability has first been noted after patch 2.0.1.
