Don't know if this has been brought up before or is secretly planned by the devs, but a deathmatch version of Flayed Hills could be really, really fun. Not serious or particularly viable for competitive play, but the sheer carnage would be spectacular. Fleet battles would bring a whole new level to the game. Right now you get some occasional huge, entertaining battles in Flayed Hills but the Crazy King format means there are rarely full on engagements, and matches are often quite long and a fairly large commitment to jump into. The deathmatch mode would have more frequent engagements that involve a larger proportion of the teams, and allow more casual, faster games that would hopefully fill up a little more quickly. And did I already say "sheer carnage"?
Right now 4v4 isn't getting enough love. Put the "fun" back in "lag"!
