I played it a bit if anyone is interested. It's pretty fast paced from what we're used to. Players supported is much higher, so games are significantly more action packed.
Rule... Could there be a rule to ban players abusing the 'main' system? Sometimes, a player will die early on as a 'main' then leave the game and return, allowing a different player to then become the main that died. That or they'll !afk and it'll put a new main in their place. Personally I feel this is abusing the system and promotes unfair play.
Hordes take a while to get to players, and they're not exclusively targeted on players unless they're boomed. Now what would be a good addition is to allow us to upgrade hordes to specific zombie type, such as hazmat, swat zombies, mudders, jimmies.
I've seen the type of systems you're talking about and they want a fortune for what they really are. You could build something a lot cheaper if you had the time. Personally I like lifting buckets, gotta get big. I started relatively recently and still do extract brewing. I probably won't swap to grain until I get a keg system setup.
I have a basic beer kit (Fermentors, bottling bucket, etc) and use a stove. I'm not too interested in brewing outside until my needs grow outside of 5 gal batches. Moving precious beer wort around from location to location isn't something I enjoy and it's risky to the product. I have a couple carboys and I'm looking into staging batches to have a constant supply. I've also been looking into making a keezer, but that's some ways down the line.
They shouldn't be a total replacement for molotovs like they basically are now. There are loads of molotovs and gas cans in nearly every map anyway. How much hand holding do survivors need when it comes to fire?
