Harmony runeword doesnt give correct +valkyrie skill levels

Hello!

I usually keep the Harmony runeword (tir ith sol ko) on swap on my bowazon for the vigor aura so i can move around a little quicker in the river of flames. I also summon my valkyrie with Harmony switch becuase it gives +3-6 to valkyrie. So the other day i found a Matriarchal bow with 4 sockets and +3 bow and crossbow skill so i thought " what the hell, lets roll another Harmony and try to get that +6 valk". My current Harmony in a Shadow bow have 4+valkyrie. Thats when i noticed something fishy. Even tho my bow had +4 valkyrie it only increased the valkyrie skill by +3 from 8 to 11. Math: 11-8=3. On switch i have windforce so theres no +skills there messing with me. I rolled the runeword a couple of times and now i got one +4 and one +5 to valkyrie but both of them only increase the skill by +3 as stated above. To be frank im quite upset by this, feeling like i got ripped. Has this bug always been there?

Goodnight.

For Amazons the use is skipped at +3 Valkyrie Skills, even if the runeword has +4, +5 or +6 Skills.

thats some bullshit.

Sorry for my bad english.
I will try again.

Even if the runword rolls with +6 to Valkyrie,
a Amazon can only use +3 from these +6

I got you the first time, your english is great. thanks for commenting on this issue.
