If I was Hoof id have a easy fix,,,
Remove the scout tower info on active titans,, cant see you secured cant stop when you have
Reduce TKP on some titans,, this part id need help with to make sure it was fair since I cant reach all. I think the best solution there is let TKP total equal 75%. To me its fair because they do 1 1/2 times what a guild that got 51% secure did so its reasonable to get a reward based on that.
Tweak spawns, make sure that at any time there are at least 3 titans available.
Give them 24 hours to clear or lose all secure and TKP, other parts of the game have time limits such as 48 hours for bountys and 24 for gvgs, maybe add up to 48 hours for higher level ones again feedback would be taken into account but by all means I would not have any titan sitting around for a week
If I was Hoof id also remove bonus TKP from 2nd-5th and instead make pots with those cool sounding buff names like imobolise titan, make it like a RP pack where 2nd place gets IT for 3 hours for the whole guild,, encourages more guilds to go for it as they get alternate rewards in the event they get pushed out of a secure by the domminating guilds.
that would be my solution.
