Having scrimmed Edifice at least 8 times this week so far (UGC Steel but we're performing a lot higher), I think it would be an amazing replacement or addition to the ESEA roster.
The map really promotes a very mobile defense, which makes offclassing on defense a bit more fun. My team has been using an ironman strat for every scrim, and rolled every team 2-0 (these teams are mostly from silver, but we played a few top teams in steel too).
The actual rooms you can back into on defense eliminate the fear of 4-man bombs at your medic, which makes playing medic on edifice a bit less stressful.
I don't know if it's just the other teams not knowing the map, or if we have a great strat for it, but it's working for us. Edifice really feels like an improvement on everything gpit did right, but getting rid of everything it did wrong. If you haven't played it at all yet, I honestly think it's one of the funnest maps, but I might be a little biased from all the rolls in scrims.
