in a general gist yes.
the optimal level would be the types of things i was referring to for optimal sp. when you get into sub b though there's some issues that have to be taken into consideration
Sub-optimal Rate "B" = ???
* Full Party vs. Lower Level Mobs - these should be a sliding scale. the lower the mob the less sp you will get per kill, therefore, less overall sp per hour.
* Light Party vs. Lower Level Mobs - same as above on a sliding scale.
* Solo, Duo, Trio vs. Higher Level Mobs - this to me should be in a1 because you are still putting in the effort to fight higher mobs, therefore, should get higher sp per kill, but with less people the sp per hour would be decreased.
* Solo, Duo, Trio vs. Lower Level Mobs - this is more along the lines i look at with farming. the sp would be pretty low because of the low risk/low reward issues.
* Crafting Lower Level Items - same as the battle classes scales down the farther below you that you get.
* Gathering Lower Level Materials - same as the battle classes scales down the farther below you that you get.
* Questing (NPC, Escort, Storyline, etc) - this one can become complicated because there are muliple different types of quests available. here's more of a rough outline of how they should be ranked on the type, but these are just opinions.
1 storyline quests
2 primals
3 class quests
4 company quests
5 leves
6 behesting
7 caravan
8 side quests
these would have to be on a sliding scale and the time taken to perform each quest should be a factor in deciding the amount of sp gained per quest.
edit: the issue with putting on a time frame once you get into the second subgroup is you have to take into consideration of a risk/reward system. if i am rank 40 what sp per hour should i get doing 35, 30, 20, and 10 level mobs? you can't put a set rate on them overall because each would have to be different because i am taking more risks the higher the level project i am taking on.
