I realize I've been making a disproportionate amount of posts. Let me know if it's too much.
I've found that the tactics switching thing can be a bit tedious. Other posts here have talked about decreasing the amount of keypresses to make things better. I find that, if I'm playing full-on, I tend to run with coward until I encounter something, then decide if I can take it down in a single turn. If I can, I switch to aggressive to increase my chances of hitting. If not, or I'm going to be fireballed, I tend to stick to coward and hope that I hit, taking advantage of the increased dodge. But always, when there are no monsters, I revert to coward, because there's no reason to be otherwise.
Is there an advantage to being aggressive when there are no monsters in sight? If not, I'd almost say that having different firing buttons for different styles of shots would make more sense than having to cycle through tactics during every encounter. Something like hitting "f" to target, followed by "f" again to switch to aggressive tactics. This would leave you open to being hit more often due to the aggressive stance, but since it takes no time to switch tactics during your turn, you would revert back to coward anyway unless there was an advantage again to the increased to-hit of aggressive (then you would just hit "f" twice again). If you wanted cautious, you'd have a different keypress, and a different one for coward. These buttons would only work this way during targeting mode (just like tab changes function during firing mode (from tactics to switching aim)).
Should there be a way to disable capslock? I sometimes accidentally hit it, then sit there getting shot at and wondering why the key I keep hitting doesn't work.
