So I've been playing some God of War 3 recently and thought would't it be awesome if you could fight on the back of the boss or have different bodyparts of the boss attackable (like mimiron p4 or bosses in games like Final Fantasy).
I'm gonna make an example with Deathwing
I think it would be cool if you start the fight on a gryphon/windrider that flies on his own (a defined route) and had to take out some whelps/minor dragons before you can chain-jump (think of flame leviathan) on to the back of Deathwing.
On the back there you could attack his wings but other dragons (adds) will stop you from doing so. from time to time 3 players (25man) would be picked up by dragons (like valkyrs in lichking) and dropped into Deathwings mouth, where you'd have to destroy some inner body parts (similar to the part where a player is teleported inside frostmourne) to get out again. (maybe this part is a bit off ^^)
You'd have to bring down the wings simultaneously (within 10sec or something) or else the wings would heal themselves back to 30%. Bringing down the wings will force Deathwing to land.
On the ground you'd have to chain his feet to the ground (maybe with some kind of vehicle or something) to force him to stay on the ground. When you've managed to chain him to the ground you will be able to start damaging Deathwing himself (he needs to be tanked, does flamebreaths, knockbacks and whatever). After a certain time he will free himself of the chains and rise up again, so that you'd have to do phase 1 again (a bit like razorscale )
When his health goes below 30% he will rise and start a deep breath, covering the floor more and more with lava (think of mimiron fire or prof slime) meeles could jump on him (again chain jumping or something ) but from time to time he will throw them down again. (most) casters will stay on the floor because only a limited amount of players is allowed on his back (or whatever).
So this would be an really awesome encounter in my opinion and most of the stuff has actually been seen in bossfights we already know.
What are your ideas or hopes for epic boss fights in cataclysm ?
