Well, they are slowly making things like this a LOT less necessary. Skillups are WAY easier than they used to be. You CAN be super minmaxing your gearswaps to squeeze out more damage or efficiency on things, but honestly... there's not a lot out there in the game that really NEEDS it vs just making things somewhat easier or less hassle.

It will be interesting to see how much the future UI changes will break stuff for the people that use the 3rd party junk. I've never bothered, mostly out of laziness.
