you can cast mana cycle on yourself...
but yeah let full bards cast mana cycle on other people, they heal more anyways with more int
if you are going to bard in party when there are enough warriors you're job is mainly there for dancing (o yeah, you be the one to dance and not main bard as main bard will need mp for healing others and attacking... and you are just going to be running tamobur+dance and using mana wind and discord waves)
use the absolute damage attack too if you want to attack, it heals mp too so it wont drain you, also put mana switch on wizard if main bard didn't already (or switch on all the bots running near you)
edit: and stand in front of the int chars and dont use noise

>.> at least there will be some what of a wall between mobs and ints or stand behind them so nothingi sneaks up
edit again: about rave melody... i dont use it much, but if cleric is good its fine to use... just with mana cycle on self you wont need it and mana switch helps too
