I use both, but voted click cause I use it a bit more

both, but mostly the click. 

I was raised on Diablo so of course its click for me.

RPGs used to be nothing but hotkeys (see the interface for the early Ultima titles or Wasteland), so it's pretty much hardwired into my brain.

Hotkeys, depending on what game it is. 

I too grew up speed clicking in Diablo, but was forced to change my ways when I rolled healing classes in Everquest and World of Warcraft.  Clicking just couldn't keep up with the pace of healing, and now I find it infuriatingly slow in all RPGs.

I don't care what type of game it is - if there are hotkeys, I'm using them.

on most games i use both,mainly when i used to play WoW,i click and pressed the keys at the same time mostly,but i like hotkeys a lot

Hotkeys, since the only RPGs I've really played on PC are the Elder Scrolls games.

I USE RADIAL MENU'S.

Both, but more click than hotkeys.

Hotkeys for sure.
