I really don't think gv'ers get too PO'ed when they are storming an air base and they get egged--comes with the territory.
If I have broken through a spawn and am almost to the airfield and the ords pop back up and I get egged it's fully understandable. If the situation were reversed and I were defending, I'd egg the guy as well rather than have him be able to camp the runways or vh.
I think they are in a nice gv-vs-gv battle and it's simply that and one of the NME gets killed a few times because they did not take "Introduction To Not Staying In The Open/Art of Blending In With Your Environment--101" and gets frustrated and comes back and Lanc-Stukas everything in sight because of their own lack of skills it's a bit of a pain. It's their $15 bucks, but why not just tough it out and learn how to gv. Sure, it's a steep learning curve but lots of fun to work on those skill-sets.
There's also a second stereotype where some new guy finds sees so many other players landing scalps and they cant do it in a gv or in a turn-fight so they resort to upping in a heavy pony or jug and goes over to some gv fight and eggs the tanks and dump rockets on the thin skinned gv's and then scalded-dog runs home to the nearest base to land scalps-get name in lights. Then again, HTC hands out monthly kudos for "attack" so it's actually encouraged. Kinda lame (sad really) but encouraged...but then again, their $15 bucks.
