We did a 5v5 OD-only on Niv yesterday. I think it played very well. App has it on his Twitch. The game was obviously slower but it wasn't boring slow. Standoffs seemed more challenging for offense and defense without the help of the boost core, but I enjoyed it.
I would love to do an OG rules game one day:
RL, GL, CG, GLS, LR
No hand nades
Defender made a server mod so we can enforce certain rules like those. The banlist file exists for a reason but has gone unused thus far. I'm also in favor of at least trying the proposed ideas and server mod, but getting that onto the server itself is up to Xzanth or Pop. The mod itself isn't really required, though would be sorta nice to have.
