Also: I really like the T-Rex Idea of a world-boss, tho they could push that even further: Why not make SUPER BOSSES spawn in adventure worlds. These could be as strong as a ST boss of that uber lvl, for example worldbosses as strong as Ultra DotM in U9, or as strong as hard spike in U6. Each Uber could have his own, or they could spawn in the middle of big Biomes, just walking their way around. They could be giant, destroy/alter the whole world around them as they fight (eg. Spikewalkers spikes), they would be fear-inducing, especially with growls and crys and high aggro ranges, like: "OH SHIT ITS MEGA T-REX RUN BOYS". You would have to group up through chat to fight them but everyone can join once the fight starts, and they could have rare dropchances of mounts with their skins, even auras/ships/magracers/wings. Also they could have a highly increased chance (based on the Uber your in) of dropping better gear. (For example in U9 cant drop less then Shadow 3, and drops 4+ items)
My Ideas are: The Kraken (Watergemworlds and Treasure Isles biome), Mega-T-Rex, or a T-Rex modifyd and mountet by a squad of humanoids (Jurassic Jungle), An Insectoid Queen, surrounded by a swarm of wasps/bees (Medieval Hills), a Giant Killer-Robot (Neon) or even a really bad-shit crazy one in Shore of everdark. (would give this biome more purpose as just to use CG-keys and Shapers Sar-keys).
What are your ideas for big bosses/their appearel abilitys? Do you like my idea?
