Trying to avoid bard because my DM don't like them.
What doesn't your DM like about Bards?
If it's the whole performance angle then take a look at the Archaeologist Archetype from Ultimate Combat.
May be the single most verstaile and well rounded class.
3/4 BaB, 2 Good saves, spellcasting (and the Bard list isn't too bad), Evasion, magical trap finding, Rogue talents, great skills set, lots of skills, able to wear armor, lots of goodness.
