Let me prove my point then.
At the moment, Generation One (that would be my clan) is currently setting up the games for a challenge with Mythology Clan. Let's go through the steps and see how complicated it really is to do, shall we?
1. Each clan leader discusses what they would like to include in the challenge. (Not hard by any means. Takes only a handful of PMs to do. Not to mention, it would have to happen anyways.) So far, nothing complicated.
2. Each clan must find their players. (Easily done within their clan forums, and would have to be done anyways, so therefore, still no time lost, or extra effort consumed). Still not complicated.
3. One clan must set up the games. (All this takes is the player in charge sending a quick PM to a single player to request a game be made with certain settings and a PM response with the game number. Also the creator is to inform their partner--if it is a team game--and let the organizer know they are in). Here is where you lose, what, perhaps an hour or two sending some PMs. Not such a big deal.
4. Once the organizer has received their PMs from their clan members, they put them all in nice list and send it off to the other clan. (Yep, pretty simple, not complicated, and the other clan can easily join the games).
5. Soon enough, all the games are joined and life goes on happily and merrily for all.
Do you see what I mean? It
really is not hard at all. ESPECIALLY if you have experienced organizers in your clan. When all is said and done you have to wait perhaps an extra couple of days to get everyone in their games (which happens with
ANY tournament, so it's no different.)
So, I say to you again, if you are not willing as clans to put forth that amount of effort, which is negligible indeed, why should Lack consider making it even easier for you?
