Just know that clicking makes the game much more difficult. It makes you a less efficient healer. It makes you a less efficient Dps, It makes you a less efficient tank.
No, it doesn't at all.
As I stated in my previous post it makes near to no difference, if any at all, between hovering and clicking. Saying it makes it "much more difficult" is a highly over exaggerated statement.
In PvE you have more than enough reaction time to be able to click between having to move, having global cooldowns and cast times.
It takes someone roughly ~.5 seconds. That's the average .3 second reaction time, + the .1-.2 seconds to move their mouse, from 1 point to another. Now take someone who ENTIRELY clicks. That same .3 seconds of human reaction time, + .2 seconds to move their mouse to the very bottom of the screen, + the .2 seconds to move their mouse to the very top of the screen, completely assuming they do this perfect everytime, otherwise you might have to factor in that human reaction time again. We're looking at a full .8 - 1.2 seconds from the time that person a becomes damaged enough to alert the healer, til the point at which the healer heals.
You're around double the time on average it takes a 'hoverer' to react. This is of course assuming nothing else is happening - in which this clicker would have to spend some of that 1.2 seconds left+right clicking in order to move out of whatever it is they need to move out of.
If you agree they should be using WASD(Possibly QE) for moving, then I can't possibly see why you say people should click their spells and their targets.
Now clicking the people ONLY still adds between 50-100 MS(before personal lag), but that's still 10-20% over hoverers, but that's not what I was discussing. I'm talking about the keyboard turning, Mouse running, 100% mouse clicking, got nothing hot keyed people.
And hey, you're free to play how you want to play. Nothing wrong with being a 100% clicker, keyboard turning mouse running got nothing hot keyed person. Just know you're making it harder on yourself. :)
