So it would be for S1 right? Frag maps seems to be better idea for servers without FF imo (nade rain etc.). Btw. are you gonna change some settings for TDM maps? On Purefrag and Fragmaze (which makes me wanna puke since it's been on polish silent mod servers for so long) there's a roof so no arty, but how about heavy weapons, spawn times (they must be like 5 sec. max and making a shot shouldn't disable your shield immediately), nade count/damage etc.
If it's gonna be on Silent1 then there's isn't much I could or should suggest, as I play there much less than on HC. I could come up with more maps if I remember, but as far as I know purefrag is cool (not sure if it works for more than 10vs10 players though). Headshot mode on with single pistols on that map, that's what I could play everyday.
Also, I don't think obj maps and TDM come together well, at least I would hate something like this on Hardcore perhaps it has some advantages I don't know, I'm open for a discussion.
