Sorry to hear you've had to have surgery, hope you recover soon. I'm sorry but I don't know how to map macros. If you don't get an answer here concerning the macros I recommend using the help chat in the game itself. Most of the time someone knowledgeable will provide you with the answer you are looking for. I do have a fire/fire build myself but I'm not sure if it's as good as it can be. Maybe someone better at making builds could make a contribution here. However it satisfies me so hopefully it will do the same for you. This build is reasonably tough for a blaster (in my opinion) but my game plan when using a blaster is to use it's innate God given gift. Blow everything away before you are blown away. My attack pattern goes like this: Aim or build up or both then Nuke, fireball, (by now most of the time all minions are dead) target boss, snipe, blaze, fireblast, snipe, blaze, fireblast add a fireball in there if you want. I do recommend keeping ragnarok set in fireball because the knockdown proc is so much fun with aoes. Anyway maybe this isn't what you had in mind but I hope this helps.
