Hope you have a blast!

One last thing because I haven't seen it mentioned and forgot earlier, there will be a point down the line when limit breaks and move rotations matter. For healers, I know limit breaks are mass healing and (later) mass raises to full across the board. Early dungeons it definitely isn't an issue and I don't know how rotation stuff differs for healers and tanks vs DPS. As you get close to level fifty though that'll become more relevant. Loads of sources online for rotations though, players are pretty good at feedback, and LB just need to find it and set to hotbar. LB is generally considered acceptable for some situations not others depending on job haha. If any of this repeats general MMO knowledge my apologies! I just didn't know LB was even a thing for a stupid amount of time and rotation can be an adventure to learn in general.
