The shield distro debuff seems silly (if I've specced this hard into things like EPS I'd like to imagine I can move shields from one side to another) but on paper they don't really look that bad. You don't really want to be using that many shield heals when you actually need them anyway, it's a preventative measure for the resist components.
Again, this is completely without having seen them in action at all, but I'd imagine if they're even as nasty as they're being made out to be, you can just bang BFI and keep something good at filling shields like TSS on cooldown. If the debuff doesn't affect the -25% reduction to shields from EPtS it's not even that big a deal. The chrono mines look like far more of a pain.
