Keyboard or mouse clicks...?

Keyboard, although I leave less active spells on 7-0 keys

Analog actions are most efficient with an analog input. Digital actions are most efficient with digital inputs. Converting either way loses resolution or efficiency.

If you play a game with analog movement, an analog control works best. Most games have analog camera/viewing so use the mouse for that. Abilities here are all digital so a digital button works best.

Some games are built for two analog inputs. Only these games is a dual analog controller acceptable because dual mouse isn't a working standard. However a mouse is a better single analog input because the moment arm of the function is .. Well, your arm, which has greater resolution then your fingers.. Unless your sealed in a cast or have a shattered arm but working fingers ;p

Clicking your spells with the mouse is absolutely acceptable in a game like p99. The only time I use the keyboard is when i'm playing something competitive where the extra quarter of a second can actually make a difference. Plus using the mouse on p99 to move sucks, I don't know how many times i've been completely turned around because the screen skips.

edit: I do use the keyboard to spam canni on my shaman though
