People quit, thats what happens in every game. They get replaced by new guys though. Noobs at first, but they will grow to become the new leets.
I think the biggest challenge for us atm is to deal with a problem very specific to WA: the variety of schemes.
In pretty much all other games the game modes are similar or require skills that are similar (in shooters there's things like deathmatch, ctf, assault, last man standings, etc. etc., but they are all pretty much the same: shoot the other guys and you win). In WA the schemes are all so different, and it's near impossible to keep up with all of them (i think there's maybe 1 or just 0 guy(s) out there that own every single scheme in classic + freeleague).
IMO we could do a good job by messing around with the schemes-selection a little.
First off, by limiting the number of schemes in classic league to 5. Five schemes that have proven to be well-balanced and... well, schemes that are just good for online competition.
For example:
1.Elite
2.Roper
3.Team17 with 1 standard homing missile
4.Shopper (I'm against wxw cause the maps are boring & support map whoring, but this new shopper should be played on say 10 official maps that are twice the size of the normal ones, to still make it challenging rope-wise, while staying true to the base skill of the scheme: knocking worms and using a variety of weapons from rope).
5.Hysteria... (so far we've failed to make this scheme perfect, but its most popular and perhaps we will one day find a way to avoid the obvious flaws).
IMO, it's still a good all-round league this way. The schemes are popular and it leaves out some annoying 1 or 2 weapons schemes, like BnG (whose skills are needed in hyst/elite), WxW (Shopper/roper) & TTRR (roper).
IMO those 3 aren't super for league play. BnG is often lame and repetitive (also, not popular), WxW has, as I mentioned, map whoring issues.. and is just generally boring imo cause of the flat levels... and TTRR... it's a great scheme, but IMO it's too skill-based. It doesn't really help the competition when it's often so obvious who the winner will be. IMO TTRR is better off being used for challenges and similar cups. (I do agree though, that if we kick it out we must find a way to make the TTRR-competition more interesting. I'm thinking for example about 1-hour challenges. (map gets announced at a certain date/time, after that everyone's got 1 hour to submit a time. At the end of it standings are published and points are added to the TTRR standings).
Freeleague can stay as it is, or even include the classic schemes as well, so it's truly FFA.
Apart from these... maybe just TRL? Or maybe 1 league of rope schemes and 1 of default schemes?
IMO it will help competition a lot to make the league simple like that. And it doesnt really cut down on the variety of schemes you can play. Cause there's still freeleague + ability to host cups in any scheme.
It will also help counter avoiding and playing pointless draws (clan A often picks scheme clan B sucks at, and then B picks someting A hates... it's not a good way to keep people motivated).
