Ive been smn since launch and love it. As for macros I use one to place dots so I can switch to a dif hotbar to use an int potion to boost before I use fester and bane getting me mid to high 1200s on crits. Its very versatile we normally run dungeons with 3 dps with me tanking the hard bosses. I can pull hate from most tanks and then lock them down till they have time to pick them back up. Also smn is a life saver with eye for eye and battle rez. And if need be we can heal good enough to keep the tank up in dungeons long enough for a healer to recover from rez. Also we never need ballads unless we are ignoring our aethers.

for mnk im working on mine right now. Only at 33 but it is fun. As of right now I wouldnt give up smn for it.

Also one thing you need to remember is that with smn you should make sure you lock on target before casting cause you get alot of interupts if the taget moves alot. Seems it happens when the targets name leaves the screen.
