That's awful because it means you're using alacrity enhancements instead of Crit+Surge so your heals will suck in general anyway.
It's bad for operatives in particular because we mainly heal by chaining KI+SP, which with a KI cast time of more than 1.9s means you can chain this combo forever because the cast time + the GCD from SP will take your power back to full. You can't do this, you have to pause between each cast to keep your power at decent levels. That's a bad thing.
