The OP is probably talking about how a magic using class has a lot more MP than a gatherer class and when you switch you don’t return to 100% MP. Such as your DoM class has 300 MP. Your DoL class has 150 HP. When you switch from DoM to DoL your MP changes from 300 to 150. When you switch back to DoM your MP is 150/300. So just by changing classes you lost 50% of your MP. Just have fun in FFXIV.
There have more and more people wanting to have a gather class(ffxiv gil) and a fighting class on 1 character. Such as a character and for the heck of you can choose marauder although all previous beta chars have been conjuror. It seems that melee have a distinct advantage due to one thing as MP management.
As a melee class you can pretty much switch from your botanist or miner with no real penalty yet if you switch to those on conj you have automatically reset Traquility cooldown. This gives a clear advantage to starting a melee class for reasons of farming shards and mats for w/e craft you choose.
As a conjuror we have found camping a tree waiting for tranq to be off cooldown, using it, then you can get to chop down the tree. We completly understand the reasoning behind the cooldown reset as if it wasnt there you could just use tranq at will on another job or to reset your MP on another job but man does it put a hamper on anybody wanting to be a gatherer and a mage.
