On the other side of the coin what I dont like to see is groups such as this go out and not engage in ANY RP at all....thats just bad form.
Yep, I personally think it's bad form to talk DURING battle, unless you're just plain crazy Between though, I think, and before entering dungeons and caves definitely.
Something good to keep in mind are the voiceset macros. V W T is the Taunt trigger, which, for Pyyran, is "Show me what you've got!" Not a bad battle cry.
