Yes i must admit that sometimes there are some rules that make me wonder if the only reason that they are there are to give refs the freedom to screw some teams over...
I sincerely do not agree with the sticker rule, i think it doesn't make sense as it robs the teams of valuable sponsor space.
I sincerely do not see the point in the picking paint off the floor rule, is that supposed to make paintball more like real war?
The boundary rule...it makes sense in the sides to give players a safe route out of the field, but makes no sense on the back line especcially because there are so many people that get pulled stupidly because of that rule...
About the leaving equipment behind rule...well, i suppose it would make reffing the game much more complicated if it didn't exist, for all the reasons allready posted on this thread, such as refs having to keep an eye on dropped equipment, facilitating cheating etc.
