out of the people still posting on this forum i have probably been in the most competetive nt games and i can honestly say, white outs are fine. i never got bored, i don't think anyone else did either. it was pretty suspenseful not being able to see the action, but wanting your teammates to pull through, and providing moral or tactical support over vent ( "take the tie, it's just you left." or "make a push, you only have 20 seconds left!" )
the games are very short anyways, 6 players with a 3-4 minute time limit, so seriously, white outs are fine. you have to sit for AT THE MOST 4 minutes, no big deal.
it's a competition game, it shouldn't be about constant entertainment, it should be about a fair competetive platform - and besides, i really did find it very suspenseful watching the console/white out screen while hoping the rest of your team pulls through.
i say white outs are fine, first person spec would be nice for pubs but is redundant for scrims.
every scrim we played both in the two neotokyo tournaments and the games we scheduled on our own, we used the white out system and ghosting was obviously a non factor.
