Consecraton shoudn't scale with AP at all in 1.12. It only scales with Spell Damage and have only 0.33% scaling. Now separete it between it's 8 ticks and... yes ~4% per tick. Watch Dernos SPD paladin video and his 400 SPD + JoCr - this is real Consecrate scaling on 1.12.
Seal of Crusader bugged as always and gives insane damage steroids, instead of being nearly useless as DPS seal.
