Kiting?

well there is kiting and u can also avoid projectiles
so if someone decides to kite you just run off in a serpentine style and they cant cause you damage

(add the More you know commercial here)

What ^ said, you will be able to have a whole bar just for bow ranged skills, not to mention you can roll and jump out of skills ways so if you get kyted, well it's just your fault.

I understand that they have some ranged capability but I doubt it'd be in any way parallel to rangers. I could be wrong, I don't know.

I think a few classes have some form of mechanic to 'kite'... however, for the moment at least. I have the impression that kiting will be used to get away, rather than to slow some melee player and range attack him. Keep in mind every class is viable with a variation of weapons. As a warrior, If I'm being kited by say an Elementalist. I'd simply switch to a Bow and use the environment to cover myself while I slowly knock of their hit points.

I somewhat think it won't be that big of an issue with kiting but there some classes on paper looks like they have just silly ammount of kiting potential for one is the thief with the.
Short bow infiltraitors arrow
Utility skills like hide in shadows, withdraw, shadowstep, infiltraitors signet and shadowtrap.
Ive might missed some there are some stealth skills and more offensive ellusiv abilities like shadow stepping to target but can't rly kite with that stuff unless they allow you to shadowstep to friendly targets without doing damage..

And yea as veno said there is the secondary weapon to help you deal with someone trying to kite you (ofc if u pick a weapon with another movoment closer or range)
