We already click right click.

100% yes, option to dissable if not working fine very good.

Yeah, this info about healing is needed in order for me to be sure about my vote.

It would be very animal friendly - my mouse will living longer.

Always missed holding Ctrl, but I can see why it was changed with the awesome Objectives. Like it!

Another good point.

How will this be used with abilities? Next attack, then reverts back to normal? Then have to re engage mob? Or will continue back to auto click?

Not all browsers work with that
And it doesnt work in a Flash Projector

Changing between attack types does not stop your (current) attack target. For instance, you can tap mob, start attack, off it goes.. then you need to heal, tap your heal icon (or press the key for it), and you continuously heal auto as well, then click weapon and you're back without having to click the monster again.

I will probably add this to other parts of the game, like healing other players, and skilling, but possibly not until another release. I'm confident this feature is stable as is, but not as much so if I started adding it all over the place, and don't want to delay the release any more than necessary at this point.

i wonder if this would give the slackers more actions or if it will just be used for more slack ^^

A+
You had me hello!
