Dunno about any schemes, except for T17 and Aerial. And all fixes there seem unnecessary or even damaging.
3 sec mines in Aerial are completely useless, because you can use your JP to fly by all mines that are anywhere close to your position and set them off. Likewise 0 sec is meh cause it'd be überfrustrating.
Removing crates.. *sigh* If you wanna destroy an important element of the game, sure.
SD? Also not needed. What's bad about a 40 min game every now and then? The longer the game takes the less land there is to fight on. I personally prefer these battles over the 'elite'-like setup with SD... that often end with the lucky player plopping the other guy first.
Why not remove all mines, remove crates and play on übercomplicated maps. You got yourself another lame ass bng-scheme that ends in a 'draw' every damn time.
T17-scheme works fine as is IMO, the only thing that could be discussed is limiting girders to 5 (although I dunno.. as you can read in my guide placings of girders is one of the most important strategic elements of the game. You don't want to limit them too much. Players will surely want to save at least 2 for SD, that leaves them only 3 for regular game. Too little to really get by with a strategy that is girder-intensive.
A free homing missile goes against the scheme's intentions. The idea is to collect random weaps in crates and fight the enemy with it. Add a homing missile and it will only encourage no-brain pro's to sit the entire game out on their side of the map. Without the missile players with no SD-crates will be forced to go on attack. No incentive anymore to do so if it's there.
How about decreasing HP's of worm, to say 80?
Or just play a little less... 'safe'.
Playing on open maps is meh too. What with the air attacks, or none available? What with ropes, how can you possible defend against it with a girder on an open map? How can you make 'zones'?
If it's not broken, don't fix it.
If taking every bit of non-predictable, 'random' elements from the game suits you.. play that shit-scheme called BnG.
The fun in worms is adapting to situations that you do not control. That's the challenge that makes it interesting.
Furthermore, why must EVERY league scheme only use ONE option in worms? We can alter pretty much every aspect of the game, yet ppl seem to only want to play 1 particular option in every damn scheme?? If you've got such a great element as crates or mines with different fuse times, why not make use of them, at least in 1 scheme?
Aerial without crates... I mean, seriously.. how uninteresting do you want a scheme to be?
