Its not TOO bad to bounce hate if its a VT-- ish monster...there used to be no tanks in FFXI if i remember right...

But its best to form a party at lower levels...standard exp parties usually consist of:

1-2 maybe 3 lvl spreads, tank on higher end of course.

1 Tank - PLD NIN* WAR

*In the case of NIN get another provoke at lower lvls

2 DD - DRK WAR THF MNK DRG BLU RNG

1 Healer - WHM RDM SMN(preferably another to go with it)

Mages- RDM SMN BLM BLU

For lower lvl parties anyway...formong your own parties are generally better imo. Also i recommend against pies and instead use cookies to regenerate your MP healed per tick back faster. Usually getting MP back faster leads to faster chains over pies if you are main healing(if you are NOT main healing however as a RDM..use Pies).
