First Thread, I couldn't find it posted before, there was similar posts but not exactly this.
Ok.
Flame Leviathan, LOL i know, but will be helpful for hard modes and newer guilds.
What it does - You are limited to a set amount for each type of tank. IE on 10 man you have 2 of the siege engines, 2 demolishers and a couple of bikes.
You then put passengers in the the tanks to get the rest of the 10 people in.
What this does is allow you to have the 4 passengers get their own tanks, or you can have everyone in demolishers, or everyone in the seige tanks, what ever make up you like. So ditch the bikes, ditch the passengers, and stack the raid with demolishers and dps the crap out of the boss quick.
Step one, Clear all the way up to the boss, except for the trash right at his door. Down all the towers you like along the way or leave them up for hard modes.
Step 2, pull the trash right at his door and drag them back so that they are out of his fight area. kill them all out there. When the boss fight starts stay outside the boss fighting area, he will target someone and come outside the boss area then reset.
As he resets a new set of tanks will appear, the same amount as the first time, so 2 new demos, 2 new siege tanks and the bikes. Have the passengers get out and hop on the demolishers, and if you like the other 2 passegners hop on the seige tanks.
Step 3, fight Flame Leviathan with more tanks, or use a bike to engage the boss and run him outside his area again for another reset and a new set of tanks again.
Repeat until you have enough of each tank you like and then engage him easy mode structured how you like, now how bliz dictates.
PS if you get out of a tank at any point and no one else is in it then it will despawn so unless you have no use for it anymore dont get out or you'll need to repeat an extra time.
Sorry for no screen shots i'll get them up after raid IDs reset.
