The druid in wildshape will probably be close.Ridley's Cohort said:The Rogue? The Monk? The Druid? Their non-BAB modifiers are going to lag unless they hyperoptimize their to hit bonuses.
Level 8 druid as brown bear: +8 Str, -1 size, and typically +1 enhancement from Greater Magic Fang on all attacks. So +8 non-BAB.
Level 12 druid as dire bear: +10 Str, -1 size, and can probably spare 2 Greater Magic Fang spells to get +3 on each claw. So +12 non-BAB.
