So in discussing the seasonal titans, there was a suggesting of making a titan that had personal TKP instead of guild TKP. It occurred to me, that the Elemental Titans are basically set up that way, albeit within a quest, so TKP is not used.
So, I think it would be cool to have some new titans that are similar to the Elemental ones. They could just be higher level Elementals, so an extension of what is already there just higher level, or they could be completely new in some way so as to be new for everyone.
I have also always envisioned a titan that slowly moves across the screen for the duration it is spawned. So it could start at one side of the screen, and then when so many kills are made or so much time has passed, it moves one square. Once it reaches the other side of the screen, it is gone (maybe to just be spawned somewhere else or maybe totally dead, could be set up in a lot of ways). This feature would really help those who do not have fast connections.
(As an aside, I originally thought of this idea but for guilds, with some restriction like you need at least 4 members on the titan to be able to kill it, but I realize that would make it very difficult for smaller or less active guilds. But then again, not every feature of this game has to be available to everyone, but is probably a different debate)
Anyway, I hope this thread can lead to some creative discussion. A big item to discuss is what the reward for killing the titan is. Could be an epic item, or could even be an epic chest. Could be bound or unbound. If several titans are created, could be resources which are used to create something.
