thanks for the reply!

I don't have any resource issue with my Paladin due to I can replenish my MP (using Flash) to keep the aggro.
my main concern with Warrior was if I spam Overpower, I may run out of TP (since they removed Flash from Warrior's cross-skill) for the next fight.
I will try tomahawk, pull 1 to 3 groups then overpower x2, after that I will apply Storm's Eye, then overpower x1, then rotate butcher's block based on which target needs attention(?)
