Productive Downtime
‘Worth it’?
Probably not if you worked on the points simply for that, but I’m finding the Tyria masteries simply come along just playing, I’ve done a few point-reward achievements that I was always going to do anyway and a couple like the Tequatl ones I’d never even tried but unlike the HOT ones I get no sense of having to grind them.
It’s not amazingly useful but it is another step en-route to the really-quite-useful autoloot ability and, as stated above, they kinda come for free.
