Literally there's no other queen that I would have won that game with, so yes Rawrr's build is the best; although there's at least 5 or 6 other UB's that not-empty/soccer-mom would have won that game with but that's a different topic lol.
Have finally found some time to watch the replay. In fact, it was so interesting that I have even watched it without adjusting game speed once. Some remarks, if you don't mind.
First of all, I am surprised you are linking to it as a proof of Rawrrr's build survivability/tankability. Rawrrr died 7 times, while everyone else died once. 7:1 to everyone else is a bit harsh for a great tank. Mulch helped him to tp out/hold his ground until you ported in a few times, but really... didn't do him much good vs players his skill level that do not make the mistake of underestimating QoT. Secondly, this game surely shows that even with 7:0 kills ratio at 30 minutes mark, you can still win the match if you think strategically (and the strategical aspect of your game - flag capping/warscore, selling gear to get relevant cit upgrades, portal game - was extremely well-thought and coordinated). I'd say it was a Great Tacticians vs. Great Strategists match, and yeah, better communicators/strategists won in the end, despite being way behind in kills. I admit I was totally thrilled several times, like: "Geez, how do Shane and Rawwr intend to win AFTER THAT?! Concede, goddamit!" My third point is this: Rawrrr hit 15 at 32 minutes mark. The game lasted for 50+ minutes. Having Tribute active for 20 minutes instead of that big-ass Mulch III would have been a more fortunate decision, IMHO (in 3v3, I'd have removed IMHO, but 2v2 it's questionable ). However, who am I to judge? You have won that desperate match, and maybe it was, indeed, Mulch III that bought you some staying power needed to cap portal X or to hold flag Y in time?
