Well, i think that those new spells helps pretty much on pvp.. If you get your meelee skills 1.35 times higer, it makes pretty big difference from the old o.o If i caculated right, even i can make with my club 81 i could make like 300 dmg with exori gran..
So you'll probably need it pretty often if you just pvp much.
And that protect spell sounds like pretty useful, if it really increases your shielding skill 2.2 times as i've heard
