Out of interest, how would you have done them - if it's a quick explanation?
I didn't want a 20-odd priest professions clogging up the list when players initially select profession, so I split them out, and did the same thing with elementalists and paladins. This was a good decision IMO.
Unfortunately, as a result of this decision, I also ended up tabulating the priest, elementalist and paladin information separately to the other professions. This means whenever the sheet needs to check profession information, it can't just do a simple lookup, it first needs to determine which of the four profession summaries to check.
If everything had been tabulated together, this check could have been done once, and every lookup could have pointed to a single, unified table, making for simpler formulas and fewer errors.
It's all quite obvious in retrospect, but I don't actually do a lot of work in Excel, so I hadn't been thinking that far ahead at the time.
