Having extra HP is always nice. I leveled my bucc with 4 base int + int gear (~130-150int whenever I can) and I have very close to 20k hp (with eqp, could get more if i upgrade dojo belt) at lvl200. I can do most bosses comfortably without worrying about dying except for Royal Guard, that thing hits like a truck I spent probably less than 150 apr in total and it's an acceptable amount imo.
