New strategies to make use of that resource may arise, but how often do you see even low-level LFMs looking for someone with AC? Or raids? Little enough. That's not what the change is aimed at. It's aimed at allowing the people who have dedicated themselves to making and gearing such characters to play them in the content the way they should be played! New strategies may arise to lean on the AC tanks, whatever their focus, but that won't ever be a prevailing force in endgame content--there aren't enough people who have chosen that route and there will always be players who prefer faster times to lower resource usage.
You're looking at the problem from the perspective of making AC toons more attractive to LFMs, whereas I'm looking at it from the perspective of someone who has an AC toon. Even raids that really benefit from having an AC tank rarely call for such an inclusion. I'd wager that less than 1 in 10 ToD or VoD runs features an AC tank, and far fewer looked for one.
Short of giving monsters a huge boost in physical damage to go along with their drop in to-hit, nothing is going to make AC characters useful in epic quests. Similarly, reducing the incoming damage on one or two characters isn't going result in a concordant increase in free SP for casters to spend. It's very difficult to avoid getting hit in quests where enemies tend to swarm parties from multiple directions unless they are being CC'ed, and that has almost zero relation to a single AC character in a quest. As far as healing goes, mass healing tends to rule the day, with scrolls as backup from what I can tell on the receiving end. As for arcanes, they can nuke, kill or CC everything just the same with AC tanks or heavy DPS builds, except that their CC doesn't go as far with the weaker melees. AC has no bearing on Wail of the Banshee, Circle or Finger of Death, and a negative impact on Web, Otto's and Hold.
