What are your favorite skills you keep coming back to and why?
Archery because it's awesome ... well at least it is after a few ini tweaks.
I have a hard time playing without one handed, even for my mages, which is why I'll often have my mages become spellswords.
Otherwise, archery, oh how I love thee, and block.
It's not a good combo as whenever I play a pure archer I miss the feeling of a good sword and board fight, and whenever I play S&B, I miss the freedom of running around with my bow. Hybrids give me a bit of both, but also don't make me take advantage of the full potential of block and archery. It's quite frustrating.
