I would have parked the bus. I would have parked the bus *so* hard.
Sentry + heavy on 2 for 25 minutes? You can do it London, you could find a way lol.
Assuming you even parked at the start of the round, assuming they did the capping as fast as possible:
16ish seconds to cap mid and 2nd, and let's just say 10 to rollout to mid - 1/2 a minute to lose the whole map, while caution would probably be exercised slowing, let's say for an additional 20 seconds (checking for hiding people avoiding sniper sight lines etc). all told somewhere greater than 40 seconds to set up to push your last. Then at even an optimum a 40 second delay between each reattempt at pushing until the round timed out would result in the ability to push ~6-8 times presuming their medic never died.
As I was watching I even came up with a handy bus parking strat for gullywash whereby you probably could have parked on second and then baited out a repush (since they were still losing by that point and would *have* to push out) at which point you would simply turtle mid with a sentry + heavy as well. Hoping for a C&D spy to cap last lol.
Desperate times call for desperate measures lol.
Or we could all just set up gamesurge accounts and mask our IPs in irc when we pug. That would solve the problem for the most part as well since I assume that's how most of our IPs are being found.
