I'd like to add a funny story relevant to this thread. There is a group of friends who play on Bloodhoof and regularly invite me to join. One of their regular flag carriers is a 24 holy paladin with 3K health.
Anyway, last night me and 2 other dps'ers were escorting him towards our tunnel when we were intercepted by 7 or 8 of their players. Expecting a quick kill, they focused totally on the fc and ignored us dps'ers for at least 30 seconds. They didn't turn on us until at least 2 or 3 of them were dead. After that began an epic 2-3 minute battle with our fc healing the dps'ers while we finished them off. It was wild and tense at the same time. I think our fc was the only man left standing.
ANYWAY..
as we are going back for the second flag, some undergeared warlock with 550 health nabs it first, gets the speed buff in their tunnel and sprints straight down midfield untouched, with one ally druid desperately trying to catch him before we finished him off. We had no idea where their team was, but we were praying that we could catch up to him before he was one-shotted by a hunter.
TL;DR -- first cap: long, epic battle with our 3K health fc resulting in 7-8 of their team getting wiped out. 2nd cap: 550 health newbie sprints down and caps untouched.
It's unexpected games like that which make WSG so much fun.
