Random crits are the LAST thing on my list of concerns. It wouldn't bother me at all if we kept them, I just wanted to bring it up in hope for change, but I'm still content if we keep them.
My big issue is respawn time. If we were to only deal with that, I'd be happy. I'd LIKE to turn off all-talk when the server is more crowded, but I can always just not play at those times if I find it too noisy.
Ideally, if we're going to stick with this all-talk deal, I'd like to change it so we just have a secondary all-talk key, in addition to the default team-talk key. One of my old favorite servers did that and it worked extremely well.
