Base-
Why -4 for even the base?
The evasion reductions are fixed so, to me, unless those reductions as CP add up to -2, I don't see why that one perk should be seen as anything over -1 sp. Also, I feel like the obtaining of subtle elements wind really isn't that steep. Haku's bloodline was supposed to be the premiere ice bloodline and ice being wtr + wnd, is it too far fetched to let it slide? Even then, if we say that ice is tier 1 so -1, adding wind -1, and adding a fixed evasion reduction perk, that is only applied to ice techniques and only lasts 1 turn. -1.
At that point, maybe -3? If we get real strict with it. Before the remake, base was -1 for all the same things.
White Frost-
Again, why -4? Is it because of the 75% chance to inflict status effect? I feel like I could see this skill without bloodline flavoring get approved for less, perhaps even -1 or -2. It's just 1 perk that is specialized rather than generalized. "ice ninjutsu" specification.
Cold Sorrow-
Another -4 but I don't see why. Specially when it's specialized towards ice ninjutsu, not even all just specific elemental ninjutsu. Also, are we still working crit as percentages? Or am I just understanding it wrong? Cause at a crit chance of 10, are we adding +5 (at genin etc.) or 5%? Cause 5% to 10 would be half a point increase. I've been away, for a while and not just that but haven't got in metagame for 3-4 years maybe?
What is the going rate for a crit range increase skill? I think the premiere crit-fish is Tsubasa, is any of his crit range increasing skills -4? Like that fatal crit skill?
Just putting a my ten cents in because this stuff will directly effect my character and atm, turning even the base level into a -4 will cause some scheiße with my skill point tally. (wouldn't be able to swap out the old with the new cause the old wasn't -4 and I don't have -4 sp to give up)
