Hello, I try to play a bard...or rather I deliberately play a pretty god awful bard IC. I use macros fairly extensively but Like Odette had surmised above one has to still manage to interact with the situation at hand lest the macro seem stilted. If you take the trouble to learn the process you can customize the macros pretty fast (a weak but viable solution) or you can break a routine into a great many macros and use the moments in between clicking them off to clarify, amend or specify elements (this is the process I have come to use). Also, given different environments, different styles of presentation become more or less appropriate. Given a large gathering with lots of different rp tracks going on, leaping in with 50 lines of successive posts is difficult to deal with at best and inconsiderately distracting usually. In those situations, single large posts are better so that interested parties can choose to read it, and the disinterested can just let it scroll on by. If however, one is in a situation where one has the attention of those present, line posting is far easier to follow and gives the illusion of tempo (if you want to get that into it). My advice is to master both.
-my 2 gil worth, Hope to perform with you in game!
