Nope. I'd rather my raises not be artificially limited and only be constrained by my MP pool. I generally only need to raise with swiftcast, but I've pulled enough groups back from the brink of failure without LB3 that I know the value of being able to raise when I need to.

I think outside of cutting edge content where dropping your rotation can be the difference between success and failure, if a healer especially is worried about their rotation instead of supporting their party then maybe they need to rethink taking on that role.
