GMT destroys everything. Long time span of event destroys everything.
From mine experience, every event that is longer than a week and asks for coordination between players from different GMTs are prone to be fucked. And, that is nicely said.
Good event with large hype produced with good presentation can last longer, but it is still doomed by two things mentioned above.
Also, majority of people that played this game and was ready to invest themselves into community through unorthodox contests are gone. Just... Gone.
I have prepared in my 'little notebook of events' things that would be grand, awesome and totally original in every way, but when I come to forum, scroll down through events and see what is happening with them, I know I just lie myself that it would work.
General lack of enthusiasm. That's all I can see.
Big events need big staff to organize them. People that you can count on. There is no people like that in TB anymore. Cruel fact. Also, big events need backing from the 'upper staff', which usually lost their elan in overburden bureaucracy or just can't see their 'calculation' and interest in it. Another cruel fact.
I'm afraid that times of big and awesome events have past. Today for something like that you would need an army of people boot-kicking lazy bastards to move their asses to do it, together with another army to do the same for TB users. Impossible.
Another thing is: if they don't see big fat prize of TC and items, they wont even consider it to apply for event. Inflation or whatever, maybe greed, just turns away many potential contestants, leaving it all to newbie players that don't comprehend 'complicated' events, well, it might be an age related thing. Idk.
I've thought to start one last grand event, forum-based, with minimal 'ingame' input, bypassing the GMT problems, that would cover all clans willing to participate, but... As I said, every time I lurk on forum to see how people are responding to some stuff, I just know it would be a just one big fuck-up and complete waste of time.
