4 AP for 5% isn't worth it.
I generally take I and II on permaforged, but that's b/c that 5% turns into 9% with some of the gear I wear (adds instead of multiplies)
think about it.. a cure mod probably hits a normal fleshy for maybe 30-40
so take 30
HF I - 30 x 0.65 = 19.5
HF II - 30 x 0.70 = 21
for a lvl 5 barb with 130-150 hp.. 2 hp isn't worth 4 ap at that level.
take an 850 hp barb with a heal for what 450?
HF I - 450 x .65 = 292.5
HF II - 450 x .70 = 315
not a great difference.
fortunately a well played barb doesn't sit at 65% or 70%
my wf sits at 90% with ship buffs, or 80% without at lvl 2 and at lvl 16 I hit 150/140% healing amp
will be 160%/150% when I'm done tr'ing.
Not all warforged will get that much, but with HF1 and leviks bracers they can get close to being normal at least.
0.65 x 1.2 = .78 = 78% healing amp.
even if they go to HFIII for TEN extra points
.75 x 1.2 = 0.9 x 450 = 405 heal
.65 x 1.2 = 0.78 x 450 = 351 heal
50 hp ain't too too big of a deal when ya sit at 850-1100 hp and you play your guy right.
thankfully, i sit at above 100 though
ANY melee WF that doesn't take healers friend I is a let down.. they can use my math against me and with gear it works fine, but 15% is really really cheap for 2AP
