Some things I do not like.

You might be able to save yourself some trouble by picking up a gaming mouse. You can assign the the keys on a gaming mouse as substitutes for shift and control, and depending on model, it may be within the range of motion your fingers can tolerate. Even a cheap one with two or three extra buttons can make a world of difference.

And don't worry too much about flowcharts and all that garbage. That's really only useful if you're going hardcore. For the average player, avoiding dropping your combos and using your cooldowns/off gcd abilities as they come available will do just fine.

No. I use the mouse. However, when solo without a tank, I do sometimes hold E while running around a mob and still use my other fingers to cast while running, assuming I'm on a smn phase that has instant casts. Basically strafing.

I have a razor death-adder, which has a two buttons on the side. But, I'm retired and can't easily go out and get something more expensive right now. But yes, that's been suggested.

The good news is that cheaper off-brand models tend to be almost as if not every bit as good as their more expensive name brand counterparts when it comes to gaming peripherals like a mouse.
