Arz: Human Paragon gives me an extra feat, better HP, an ability increase and allows me to select my skills and increased Bab, for a gish I think it is worth it.
sirpercival: Dragonslayer 1 advances casting, gives fear immunity, has bab +1 and gives all proficiencies (weapon and armours) with save for the BAB requirement, neglible (Dodge, Iron will and 2 ranks in tumble) in short an awesome dip for any gish, but the requirements kill it, because then I could go into Abjurant champion at that point.
