I'm running a BF paladin right now.
Has all the usable racials, has divine might, has sacred stance ,all I don't have is Harper( cause it's not live )and I got points to spare.i
Not sure if you know this, but to get the top tier racials doesn't cost many AP, you can get it with one core and skip most of the other enhancements if you want.
BF is a top self healer, not sure why you are saying BF is for non self healing builds cause the racial repair out performs all the heals and repair spells.
With an epic ring of artificer or similar repair amp on Thunderforge, the crit repair can be over 2000hp ( I have 3x Bladeforge lives )
Because the BF has such an excellent self heal and repair amp, there is no need to waste spell slots on repairs or heals.
Burst?
Power of the forge lasts for 20 seconds and is almost immediately reusable again, it also does not share a cool-down timer with fighter haste boost ( if you opt for fighter levels )
20% damage bonus........ That is .. 20% damage bonus, 15% melee speed, +4 to saves and how many boosts... 11-15 x20 seconds every shrine.
CiTW weapons also benefit from the shield mastery, the rapier tier 4 , red slot meteoric and planar prowess , so that's actually even more PRR because of the shield mastery, thanks for reminding me.
I'm just not sold on humans since BF was released.
I will admit I have not tested U23 content yet and can only go by my own builds and player experience.
The only advantage I see as human is you can TR at lvl 20
When all is said and done.....Swashbuckler dps will still dominate
