Trying to get back into MS

I'd say that either an I/L mage or any warrior would be the best classes for the Monster Carnival. Mobbing skills help a lot in certain maps.

Thats why clerics are great too. Spamming Master Chronos is a very common strategy and often not done wonderfully; when I cpq on my cleric I love when the opposing team summons them.

Regardless, for the TS, for a CPQ class I say cleric or warrior. Clerics are nice, with heal being a nice asset. Warriors do a nice chunk of damage at once, which is very nice on the rombots (plus slash blast just kicks ass).
