Godlike I'll put it back onto you,
How does Seal of Insight or Seal of Justice help a DK in arena? I can think of one situation where SoI could be benifical and I'm not even 100% sure that SoJ is in the game?
Deep Freeze and Chaos Bolt are practically useless to have on a DK, unless your playing with the same class and can have the other spells required to make full use out of those spells (Frozen target/immolate).
Ice Block and Divine Shield are wayyy too situational, how often does your opponent block/bubble when your under pressure and need a reset? Never? Assuming you managed to steal an instant cast spell, your going to have it for 20 seconds... and most likely not use it correctly.
It's all well and good to copy/paste from another site and claim it as your own, but don't try and claim your 'a high rated pvp player in both rated battlegrounds and arenas' because your going to get called out and look silly.
I'm not a high rated player at all and I can pick apart the spell you've selected.
