I dont play DTV much but ...
I dont think you should see the end wave without having some really good team.
Simple fix would be to play "Defend the Virgin in a field"
That's the thing: devs and admins
don't play the mode,
so the people responsible for it really have no clue.
Bad teams who roof camp usually wipe on Vitez (if not sooner). Sniper crossbowmen take care of that.
So even with roof camping you
don't see the end wave without having a really good team.
As I said in my first post, I would very much welcome back open maps:
IF the spawns were staggered once more. I mean have 1/3 spawn nearby, 1/3 spawn far away and the last 1/3 spawn even further in the distance. All within a cone of maybe 120 degrees (give the players a safe backside, at least initially)
Right now, having a massive wave of bots all clumped together is just cheap and overwhelms even the best teams if you fight them without staggering their arrival.
