First time MMO player here unless you count my week on DCUO(blah). I enjoy being a THM soon to be BLM and I don't see many other's on the Leviathan server :-) I have lots of fun creating "beginning the fight" macros that help my groups Tank for his playing style. I do wish people would put more time into learning and teaching the beginning levels of THM as it seems to me it's all about level 50 rotations, well some of us have families and can't spend every minute of every day playing FFXIV so it would be nice help the newer players with beginning rotations to help with the lower level dungeons. I've learned on my own and learned the hard way by doing it wrong in the first few dungeons.

starting a fight rotation

Blizzard 1 or 2(cast heavy)
Thunder 1 or 2(DoT: Damage over Time)
Blizzard 1 or 2(keeps the UI: (Umbral Ice) going)
Aero 1 or 2
Transpose
Fire 1 until around 100 mp
Transpose

I repeat if needed but usually go into Blizzard/Fire rotation after this

Hope this helps newbies like myself....
