I use Benison as a pre-pull shield whenever I have it available. It's no Stoneskin, but it's something. It can sometimes mean I don't need to use Tetra when they pull is complete, and can just whip off a quick Cure II to get the tank back in good standing. I use it because I'll get the lily back in no time so I can use it for things I really want when we're working on the trash, like the reduction on CD of Tetra or Assize.
I also try to avoid having regen up at the end. I'll go over to popping a couple Cure II's as we finish instead of re-applying regen so it won't go into the next pull. I know tanks can learn to adjust, as we were expected to learn to adjust for people not dodging. But I don't see why I need to put strain on my party by not doing what I can to avoid issues.
