Judging from your medal i assume you haven't partook in the activity much. 51% is very challenging against the right competition. The issue remains how to bring that competition back. Messing with secure for sure will kill TH in general no questions asked. It's hard enough to justify doing 51% for a measly 10 fsps for some items.
What makes seasonals so competitive is because the limited time frame. I do believe the spawn rate in seasonals is too high but that's besides the point. How can we replicate this for regular titans. I have a suggestion to this aswell.
Step 4: Obviously the most controversial one and is optional but i think it would aid overall. Discontinue cool down as it's negatively effecting TH. There are a limited number of TH to begin with making them wait a week before they can hunt again doesn't make sense to me. Because they are on CD titans just sit there unkilled and uncontested. I can see a need for cooldown with 1000+ hunters but let's be real the number is in the double digits if that now.
Not that we all needed a glimpse into your true colours but hey let's throw the gripe out there, you dislike being on titan cool down and your numerous reasons as to why never serve any logic beyond having a monopoly for the guild you inherited.
One of the big reasons this game is a success for and after all these years is because of it's Organic Nature, it's never perfect but what world is?
Admins have thought long and hard concerning the restrictions that they have put in place and for what? Yes, to make the game playable for the playerbase not succumbing to some irrelevant bods idealistic irrational rants.
As it stands I don't believe any decay or heal time should be placed upon the titan system, they are what they are, go hunt the beasts for secure or tkp, if it sits after a secure then go finish the beast off and stop wasting everyones time whinging that no cleaners are doing the job for you.
