I think it would be really really really cool if you could use special abilitys with your pick, tree axe, essence syphon, etc. on the reasource you are gathering.
Just think...being able to multi-strike and critical them little piles of resources , it kinda makes sense that you would be able too, whats the difference of hitting a big golem with your normal axe/sword, and whacking a dead golem/ore pile with your pick I dunno, I think it would be fun for us and all those craft nuts out there, whats every one else think of it, i wanna hear it
