It can be a trade-off, but it is not consistent with the rest as described in the feat's description (i.e., subtract X from BAB and add X to AC).Thanee said:One feat (Combat Expertise), that's the trade-off
Also, if you check the description of Fighting Defensively in the 3.5 PHB (not the SRD, the physical book), it explicitly states that it stacks with Combat Expertise.
And 5 ranks in tumble plus a feat (TWD) give you a +5 to AC for a -4 to hit.FreeTheSlaves said:Don't forget that 5 ranks in tumble makes that fighting defensively AC bonus a +3 instead of +2.
It's pretty cool for mr whirlwind to get a +8 AC when he needs to hold out for another 2 rounds.
