A paladin for the Arena

[Arnulf]

OK, I don't get this

According to me_irate over at the Basin:
So 100 Spell power adds 20 damage to each proc of SoC right?

100 Attack power would add 100/14 * weaponspeed or approx 25 to each hit for a 3.50 weapon and would not only boost the SoC but would also boost about 3 autoattacks for each SoC. So 25 * (3+1) = 100 meaning 100 Attack power is about 5 times as good as 100 spell power

Is my understanding of the game mechanics not correct?

I cannot say anything definitive about this, since I use JotC + SoR (never had Command).

According to this look at post #4 spell power is better than attack power because holy (spell) damage cannot be mitigated by armor.
