A misunderstanding I'm seeing in a lot of these comments is that when a tag-me deck uses AS, they're doing it for the burst economy a lot of the times these days. Yes, there's the -5 for the corp, which is a big deal, but as the corp I won't let the runner have siphon credits just because I can recover. I do my best to make sure that they either want to remove the tags, they're going to have to pay through the nose such that it's not an economic boon, or the creds aren't there when they get in.
The best thing about AS these days is that it can turn you into a rich runner; as the corp, you often don't want this. Taxing ice such as Komainu on HQ or asset rezzes protect against this.
Even if I'm a rich corp, letting the runner get rich is usually a mistake if I want any kind of remote play. That said, if you're NBN, maybe you care less because you're running Shipment from SanSan and don't need that many credits.
If you're playing any sort of glacier, you need to be aggressively icing HQ still because you need those piles of money you're making for yourself.
I think we see less AS because runner's can do other things for money these days (kati, security testing+desperado, aesops/cache, voicepad, etc). Aside from curb stomping opponents, AS was always about the money. But it's not the only way to get money these days and isn't the most efficient against a wise player either.
