Some questions

[Lax]

1. No, you do not need to make any changes to your action bar keys. However, by default, only 1-= will be done with the FTL-based auto-assist. You can copy the mapped keys made by the Quick Setup Wizard and have the modified versions work just the same (e.g. add new ones for shift+1 through shift+= and so on, exactly the same as the 1-= ones).

2. No. Not all keys have, or need, FTL. The FTL only applies to the specific "Assist" "Follow" and "Target" functions -- everything else works as-is

3. Correct. You will not need [target=targettarget]

4. You can keep your existing G15 setup if you prefer. I like to disable the Profiler and set up these keys directly through ISBoxer instead of through the Logitech profiler. This allows you to write the macros in ISBoxer instead of in the game, AND bind them to the G15. That is opposed to setting up a macro in game, assigning it to something like ctrl+shift+alt+z, and telling the G15 software to press ctrl+shift+alt+Z. In other words, that whole process is given to you in a single interface. To keep your existing G15 profile, ALL you need to do is run the Logitech Keyboard Profiler as Administrator, and use it as you always have.

5. 20%-ish. The Wizard does not create Repeater Regions or explain them to you, for example. However, nearly all of it is handled by the Quick Setup Wizard. Zanthor has been a little busy and has not had the time to update the guide to add the Quick Setup Wizard usage -- and it would have to be retitled to Zero to Hero in 5 minutes instead of 30

6. Only one way to find out! Feel free to request a trial. With that system, I don't foresee any problem though.

7. Drag the one region so the red area covers the entire Grid. You don't need different ones unless you want separation between the regions, or if you want to send the mouse to other clients. For example, some people have found it useful to send the left half of unit frames to a main healer, and the right half to backup healers or other characters for buffs.
