Yeah I don't see how a fac other than spiders is supposed to win here.

* Vehicles are non-starters, obviously
* Shields get fucked by spiders at every stage of the game on most maps, let alone this one.
* JJ are awkward but the contours of the map favor spiders over them
* Cloaky can't properly play defensive because spiders gets too many angles of attack that cloaky can't defend all at once.
* Amph is another fac that has a hard time against spiders on most maps, let alone this one.

I've noticed a lot of jump/shield/cloak players have all converted to spiders for this map. The venom change makes it a great choice. That said, other factories CAN win, you just have to be very careful about how and where you place your porc*, then spam things like sling, firewalker or badger.

*This map contains a great many natural terrain wall for recluse to fire freely at stingers. Your porc needs to be a little on the tucked back side.
