Been playing since 2006 and I use it when it is easiest. I use it mining. When I am fishing in Krasang wilds in the big lake there are 5 or 6 spawn points in the lake. If one appears, I stop fishing and get in the water and when I see the ore, I click it and therefore swim to it. Once there I have to stop and click again to mine it otherwise I get a warning that you cannot do that (ie mine) if you are moving. Also, if the node is too far away, even if I can see it clearly, I get an error message that the target is out of range, so I have to swim closer and then click it. I assume the bots you know so well have macros to cover these 2 errors as I deal with them. I do not bot but I use click-to-move a great deal from getting from A to B and would hate it to be removed.
Mainly I wanted to say, not thinking I am a unique player, if I am using it, many many more will be, and it has nothing to do with botting or being a really bad player. If 1 click gets me from A to B, why should using it make be a very bad player. It speeds up my mining a bit.
