Camera speed, deceleration and auto attack ON/OFF

If there is a thread opened about this question of mine, delete this one and just send me a link if you can since I am new here and I am not sure if there is a thread already made about this.

Is there an optimal setting that pros use for camera speed and deceleration? I've seen some commentary from Merlini about this, but since options are changed now, and there are other rules of thumb for camera speed and deceleration now, I am not sure if it is a matter of preference or there is an "optimal" setting for those. Haven't seen any good discussions on that topic on the internet.

And my second question is about auto attack setting. I 've seen good players with the setting on and others with the setting off. I am generally aware for the pros and cons that both have, even if the pros for auto attack OFF are more than those for auto attack on, except the lazy S right click S, for hp trading and harassment which can be done with right click on target hero and right click on other place, but still, I want to see your opinion about the subject.

Sorry for my English, it's not my native language.

I can't exactly help you with the optimal camera speed settings as I just move my mouse around quickly :3
however you should always turn auto attack off. If you want to auto attack just use force attack and click on the ground; that way you will auto attack everything that comes near that point or anyone you encounter on your way to that point.

I disagree, turning on autoattack is NOT worse.
It just depends on personal preference. For me it helps a lot with timing hard lasthits well by using the stop command and autoattack.

And it doesnt depend on player skill at all, i know that for example dendi has autoattack turned on.

Agreed, it all comes down to preference. Personally, I have it turned off, as I have a good sense of rythmn, so I usually prefer to time a single Attack each time for every Last Hit. I also have "Auto-Attack after Spell" turned off, but I do occassionally miss it when playing Dragon Knight or Storm Spirit, since those guys are good for mixing Auto-Attacks in between their Spells.

I don't know why people think some settings are good or bad, or why people hate Legacy keys. Then again, I could probably make those people cry with Rage if I showed them my Key-Bindings (Custom Legacy with a twist) 8{3

I guess stuff like key settings is a personal preference, that's always the case from my experience with the previous games I've played.

But what I am interested for the most are the camera speed options since I believe there is some range of camera speed and deceleration which is more preferable.

I only know that commentators lower their camera acceleration to make it look better for the viewers.
