Except that the AF and IAF have to be toggled off and on if you ever wish to use IPS with that AF/IAF buff. that's not happening. youre going to move, a lot. to line up your ips targets better, to avoid ray spells, arrows, kite mobs. there is no where, aside stationary boss fights, where youre getting full af/iaf stacks and then using ips. prowess turns every boost into 100 power. it allows ips to use all that power where af/iaf builds could never.
You should easily be able to hit 50-56 wisdom with end game gear now without trading off much of anything.
Which is almost the difference on it's own.
You also get another 20 RP from from new set on Boost and it lasts longer, and more like permanent 20 because of increased duration.
Without AF or IAF on a split (which 5FS is defintely not talking about, he's talking about being pure), you're already looking at 70 RP versus 100 from Prowess and 40'ish from Henshin.
The real question is can you make up the difference of 70RP (140 - 70) with the 28'ish AP sunk into Henshin and VKF.
I think having all those points for Half Elf makes it close, because of the 3 SA dice, 3 Dex, 3 Boost Dex and 3 Boost Wisdom for 10k, along with Healing Amp and SA damage range. In top of all of that, against red names where you can stand mostly still, you can get up to that 45 RP from AF, which actually once you get it stacked, isn't that hard to stop for a couple seconds and start restacking it, and it doesn't decay that fast.
You could also do a little less in Helf with the extra AP and dump them into Harper for a pretty good sized gain (9RP, 2 or 3 Dex, a couple extra base damage, and like +10-12 base damage from KTA). This alone is probably just as good as MP build.
All I'm trying to say is, 5Fs is right that these things are not THAT far apart. He's not arguing RP build is better, he's arguing it's not much behind. I think he's right.
