Yes, no problem there.
I just wish groups would be more upfront with their face rules, and specifically who bears the burden of responsibility in most common situations where a dude gets a mouth full. A demonstration of what an airsoft gun does to a watermelon every now and again would be a good idea.
I think a lot of players run without a cage because if the salty old guys do it it must be fine, right?
In reality, the salty old guys either have a good dental plan, or figure their teeth are bad enough it doesn't matter, or are dumb as doornails.
I fit into the latter two categories, fully consenting. I honestly can't help but roll my eyes at disputes I've seen or heard about.
