Thanks for the reply. I see your point, but I think I left out a pretty important part.
Player A was in a hog.
You know, I thought of that after when I re-read it and meant to add to my reply.
In that case, all the more reason that Player A needed to keep moving. He can't stay stopped for anything. Perhaps if the gunner was coming through the portal on first cliff, and the 2 players were on a vent together and the driver knew that it might be acceptable for that second to wait but even then it is grey. Player A is not progressing to navs and he is also now taking a hog out of action.
There are a lot of grey areas here :
How long was the wait by then? Had the teammate got involved in a fight when he spawned at a base and been delayed?
If Player B fell down and out of his hog right in front of Player A's hog he might have thought he was potentially about to be run over and defended himself. That could possibly be a valid argument.
If Player B fell down and Player A wasn't in the drivers seat, but was maybe in the passenger seat for whatever reason, or on the guns while waiting for his teammate then he is fair game, regardless of whether he fires or not.
If Player B fell down, wasn't in front of Player A's hog so no chance of feeling threatened that he should have not killed Player A.
I do think if its as you say then it seems a bit of a gratuituous kill on Player B's part, but then again I have a strong issue with Player A just being parked there.
End of the day though? Player A should never have been just sitting there. With or without a hog. In Sidewinder especially it is easy to team up, given the portals from cliff to cliff, there's really no reason to sit still anywhere for any length of time. The hog could have kept moving, get the first cliff (if he didn't get it before falling down) and head to second cliff. If his teammate spawned at Blue and was taking portals he could grab First cliff and go back through to 2nd and team up there or at blue base because quite often you can make that trip faster on foot than the hog can. If coming from Red he could take portals through First and on to 2nd and still team up there or at blue. Can't just park and wait. Or he could have stayed moving and at least have headed back up to wait for his teammate AT the tele's (for just a second), not down below. In most cases by the time they drop back up the ramp and across the bridge the teammate should be just about coming through the tele regardless of which base they spawned at. What if he spawned and got into a firefight at the base? How long is ok for Player A to stay parked and wait?
Tough call depending on the details but I would lean towards Player A shouldn't be parked there and none of it happens. If I were admining the server my first inclination would be to say that Player A should have kept moving somehow while attempting to get a teammate. If I had noticed someone parked there I would most likely have asked them what they were doing and said they needed to get moving and pick up their teammate on the go. Our rules state that you must keep moving to nav at all times, though we allow the exception to briefly hide if you are alone and avoiding a loaded enemy hog.
Take it a step further. Player A is hiding under the bridge, where he is mostly out of the line of fire. His gunner comes through tele, jumps down, hops in and the hog pulls out from its spot under the bridge and the gunner immediately has a shot at a lone enemy hog that came along to go up the ramp. Is it fair for him to kill that hog? popping out of nowhere like he did? Not really. Especially if the hog is a lone hog. Maybe if its a loaded hog. The whole situation just become muddied.
Hope that helps
