I like auto atacks. Especially if it blends well with the materia system being able to be used for procs. I am leveling lnc/thm combo with a little con mixed in, to make my ideal debufferish type character. Its working well, but if I could have a way to add materia to weapons to get benefits such as procs, my ideal would be lifetap proc. IE, every swing I connect on a mob, I have a % chance to do a spall life tap through the power of my weapon. A multitude of procs could possibly be added to weapons this way, possibly. The same goes for armor, and armor procs as a possibility.

To top it off though, I agree also, with alot of other posters, that the ability to actually still get a least some damage in, while typing to friends/Linkshell mates/group mates and what not is a great plus.
