MR_SLINHereThereBeTygersMaybe they could stream, but not save the VOD? That way the other teams would only be able to see all the little things that seanbud mentioned if they watched the stream live.
That's a slightly better option but you're still putting out your pov, strategies, comms, etc. out there. I completely understand why people don't want to stream scrims.
Your comms being listenable being a disadvantage? Seriously?
You're suddenly at a disadvantage because the other team knows that you can communicate when things die or how much damage you've done?
This may come as a shock, but every team that has ever been dominant in this game has only been so because they had the best dm there was. Sorry to burst the theorycrafting meta-bubble, but just because you run a heavy on last instead of a pyro doesn't mean that you're suddenly going to be taking rounds off of teams that DM better than you.
