I used Dante 100% of the time and I never saw him useless. His stinger is the best for grinding since it gives a chance to instantly kill an opponent regardless if they null/absorb/repel Death attacks. Has 3 undodgable attacks. He also cannot be Fused/summoned by The Minister or Mido which should show just how strong he is. He's good for the extra crit turns for Lucifer unless you're playing Hardtype.
