Just an idea. I think battle with titans should be:
If the titan kill will happen once in 3-6 months, it will be very good, the guilds will develop their strategy and team cooperation for a very long time to have not so big chance to become legends (It’s such a big news that someone finally killed the titan, the slayers’ guild will surely become famous soon after finishing the battle). Only the cleverest players can slay titans. Titan fights must require very good strategy and team cooperation and depend on fighters’ intellect rather than on their wealth.
Titan fight must not be boring. It should be very unpredictable and require skills in different areas of combat system. You must act as appropriate and think fast. Only if you’ll have a successful strategy AND will actively cooperate with other members of your guild AND you and your guild members will be a very skilled players AND clever humans in real life, you can defeat the Titan. Also the Titan fights must be entertaining, the graphics must be on higher level, than in the rest of the game.
So, this is my idea. I will be very, very excited if at least one of the Titans will have the fight as I described. Sorry for my bad english, my emotions interfere with my mind.
