Sorcery Ward recharge timer considered a buff

I realize this is probably not a high priority issue considering the copious amount of problems PoE2 currently has, but for some reason, the Sorcery Ward recharge timer is considered a buff and therefore negatively affected by "Buffs on you expire X% slower". This stat is on the only real "skill effect duration" cluster in the Merc part of the tree, so it's unfortunate that I can't really get the skill effect duration without nerfing my sorc ward. If you could fix this, I think it would make more sense to have sorc ward charge time be separate from buff duration.
