I've always disagreed with not allowing a second buff.

1. Only 1 buff => your subjob is at 50% potency.
2. Only half skill/nerfed results => your subjob is at 25% potency
3. Only a limited amount of songs/abilities to choose from => your subjob is at about 10-15% potency

If this applied to other subjobs, cure would for example cure II would heal for 15 instead of 90 HP. Or your berserk would give 5% attack. This idea in general would make any subjob pointless, but currently just make BRD and COR pointless. (SMN is also pretty pointless, as well as BLM due to restrictions on spells and skills).

I still don't get why some subjobs are full power and others are weakened 90%. I'd like to see all subjobs being pointless, or all being useful. Favoring all being useless just to annoy people who were lucky enough to play for years with good subs.
