(Roughly) What size groupfights are these maps meant for (e.g. 6v6, 10v10 etc)?
The first one is larger than the second one. We did 7v7's on that map yesterday with plenty of room left, so I'd estimate it could work with a 10v10 - 12v12, something like that.
The second map is smaller, so I'd estimate that is roughly 8v8-10v10 max
Depends on how much room you want to manouver, but they're pretty standard sizes for GF maps (especially pub-play)
Guess the real way to find out is downloading them
