Familiarity: I've put it through the wringer
First: thank you black diamond for not listening to the masses. Most great alpine climbing clothing and campwear is designed well at first, but altered when it's discovered that it's easier to market to the masses than to the core community (just look at anything and everything by TNF). Thank you for not going down that road black diamond. This tent is perfect for it's intended use, and without it alpine climbers would be left without a unique and indispensible piece of gear in their quiver.
Buy this tent if you ever find yourself asking these questions before a climb:
1) Should I bring a bivy sack instead of a tent?
2) are there any platforms big enough for a tent on this route?
3) Should I ditch the tent entirely and just climb single push to the top?
Buy this tent if your reaction to a heavy pack is fear. Don't buy this tent if you pack anything resembling a toothbrush.
As you can tell from the other reviews, yes it doesn't hold up well to rain, but why are you climbing in the rain? Rain causes rockfall and comes with lightening. It's dumb to climb under falling rocks in a lightening storm. Don't do it.
You get the idea. This is a climbing tent, i.e. it's a piece of climbing equipment. It is not a base camp tent. It is not a backpacking tent. It is not a car camping tent. Mine sees uses in all those functions, and it's passable, and mainly comes out because I'm lazy and goes up/comes down easily and quickly, but it's not what the tent is made for.
When it's time for a multiday alpine climb, and you can afford the luxury of a tent in your bivies this is one of the only tents on the market that even exists that you may consider bringing.
It will take minimal room in your pack (but still a lot by alpine climbing standards, it is after all a tent), won't weigh you down much more than two ultralight bivy sacks but will give your boots, socks and gloves a better chance to dry overnight than a bivy sack, it's only 4'x6' making it easier to find a place to pitch on steep and uneven ground, it stands up well to the wind, folding, but not breaking under heavy gusts (>60mph), light winds pump the walls and actually air the tent out, it goes up and comes down very quickly, so you don't waste precious time breaking down camp. The only downsides to this tent are its length, which at 6' may be too short to accomodate some climbers (although you can curl your legs up a bit and make it work if you're only slightly taller), and the way the door is attacked at the bottom instead of the side, which makes harder to keep snow out of the tent (the Mountain Hardware Direkt 2 had a better door design, but I think it's been discontinued). But if you need this kind of tent, you'll probably buy this anyway despite the downsides, because there's nothing else on the market in this class.
