Alts not engaged in combat would place signposts - whatever.

I wrote a combat system from scratch for another game. Should they listen to me instead?
This is the same discussion we had when people were using scents to summon dead alts to block or trap others in w7. The arguments were literally the same: "it's an exploit", "it's skill-based", "it's legit combat", "it's fun". That mechanic was removed so one would assume the devs don't like this kind of thing.
