As it happens, I use control- and shift- to modify my action bars, but also use the Naga as well. Having all your buttons handy and set up for *very simple* access is thoroughly worth the price of admission, all snark aside.

When i was looking for a new mouse, I started pricing out different options.
Although the naga was the most expensive mouse I looked at, the additional functionality I found was more than worth the price tag. It really is quite surprising how much it changes how you play. I can barely play on my friends computers anymore.

Read the article. Without the visual clues, the other solutions are missing quite a lot.

I like it, ronwolf.

I was a bit surprised when reading this article that it talked about the limitation of Healbot, which I thought was selling it extremely short. "Without keyboard mods, a Healbot healer is restricted to no more than five heals that are ready at a moment's notice." So what? Alt, shift, and ctrl are not that difficult to use and they push up the number of spells that can be used to 20. Yes, you have to learn where to put all of your spells in Healbot. You also have to learn where are the buttons are on this mouse and know their corresponding spells, so there's something to be memorized either way. I've also never been much of a fan of mouseover macros for healing. Having a rigid box displaying health is much better than mousing over to monitor health. Healbot and other healing addons are also used to monitor range to your targets. The box displays so much information that the standard interface has difficulty conveying.

I'm sure I could benefit from a spiffy gaming mouse, but I'm also sure that the money could be spent better elsewhere and free macros like Healbot or Grid work just fine.

Totally agree. The use of CTRL, ALT and SHIFT modifiers really makes mods like Healbot and Vuhdo shine. On my five button mouse, I rarely have any core spells that I cannot fit easily into my setup. I can see the value of having a mouse with a huge number of buttons, but I think it's more efficient and less unwieldy to use the keyboard modifiers.
