oh, and about esteel's comments on defending. He's one of best defenders I've played against on Herforst. I learned a few defending tricks from playing against him (mainly for creative use of rockets oh facing worlds)
An in regard to C.Brutail's comments about grapple..
"say try to play that map on a normal CTF server too, and decide, what's more fun."
I've played both and I prefer the grapple on that map. I've played some other maps where I would prefer not having a grapple, but with facing worlds, I think the grapple improves the map.
I wish it were designed without the anti-grapple mindset (i.e. get rid of those stupid kill zones) If you don't like to play with the grapple...then don't. But you shouldn't go out of your way to prevent other people from playing with the grapple.
