upgrading skills

[boomclap]

I'd like to know if you guys upgrade your active skills whenever possible.

Are there certain skills that don't need upgrading or do you upgrade everything?

(I know this is covered in the Archer's guide, but it's kind of confusing.)

i upgrade most of my skills...the only time i dont do it is when i dont have money for it..

[mstryoda]

I upgrade all my skills.
Can't think of any skills that don't need upgrading, cause I use all of my skills.

i upgraded my skills whenever possible... because some archer skills (aimed, power, multi shot) have casting time and of course i'd be nice for it to deal more damage!! as for the DoT skills (fury, bone), upgrading can have higher DoT damage that makes kiting easier ^^
