I find Tier 5 interesting, personally.
Noise making grenades that do not expel BB’s are allowed. They do not count as a hit.
So that leaves exactly what for grenades? Because Snicker and Tornado grenades are absolute shit, IMO. I've never seen one of either sort work right. Snickers go off the instant the spoon flips (i.e. in your hand) and Tornados just don't go off. Last time I saw someone toss a Tornado it coughed and a single BB simply fell out of the port.
Just pointing out that "field guns" (i.e. any AEG rifle) could be a "support gun". MP5 with an auto winding c-mag? Hell yeah, it's a support gun!
Looking through other parts of their website, though, it seems they're taking that rule out. Nice job keeping your website up to date, dicks.
As far as the grenades go, it's a bs rule meant to keep cheating down. IMHO, it's all geared to keep older, more experienced, and more honest players from coming into conflict with the lil hoodie warriors that would dig this sort of thing but hate loosing enough to cheat. That said, this sounds like a big money thing. Nothing wrong with than, just won't send my money that way. Vote with my wallet, as they say.
