I like how Zapier keeps referring to KUTT and mis-quoting what I said.
I said take it to the forums, because whoever it was was crying up a storm in-game when all we did was agree with you.
I also said that you don't see them implemented because it -does- take coordination. Para and I spent 4 minutes building that one, and given its position you all spawned right next to it and could have destroyed it.
It's not easy to set up unless you've done it a few times. I think the best suggestion so far I've seen would to make it de-selected by everyone at the end of the round, but still persist through the rounds until it's destroyed. Maybe lower it's health a little? Though it takes like 8-10 swings from a player with 3 Powerstrike to destroy. Yesterday was the first complaining I've ever seen about the tents, though it's been used for a few weeks more often in Siege. Most players applaud the ability to put them up in strategically good places. I mean hell, if we wanted to, we could have put them right on your flag and had our team spawn there but we put it by the gate, still 1000ft from your flag.
TL;DR (for those that are lazy) -- Don't misquote me and lump my clan in with what I say, and also, best suggestion is them staying through rounds, but spawns being de-selected so your team has to spend another 2 minutes just getting 12-15 people to set their spawn there. Lower their health a little bit too.
One thing I wish we could have in Siege would be Door-Rams. Build it up, take it to the door, and ram the door 4-5 times to take that gate down. Of course, it's just one gate, but still, would be fun to see a team come up with one quickly.
