Maybe next time a bunch of skills are updated, we can have the option to choose whether or not we want all of our attribute points and any affected skill lines rather than just having them refunded.
I haven't played for a week and I logged in for "some quick PvE" which ended in me staring at 40 unassigned attribute points and trying to remember where they'd been. The same with the skill points. Sure, it's a good opportunity to respec, but I was happy with 75% of my skills exactly as they were.
Given the option to refund/not refund, or at least some way to record what my previous set up was, would be great next time you do this.
