Some short footage of rogue and ret in 2v2, Some of these matches actually took longer then 20 minutes but i cut alot of it out. Enjoy, Tips are in the discription:)

Dont ever use repentance or blind if Hand of Sacrifice is up since it will instantly break it.
Watch out when u use ur trinket because if u use it to quickly its a waste like, When a rogue used cheap shot and u trinket it he will do a 5 combo point kidney shot on u so its better to sit out the cheap shot and then trinket the kidney shot.

When ur being trained as a Ret Paladin dont be afraid to pull out your 1 Hand weapon and ur shield and switch to Seal of Light, I dont see alot of Paladins doing this but if the arena ends up being 1v1 or ur healer is in a cc this might save ur life. When you got your CD's back you want to switch back to your 2 Hand and back to Seal of Truth, build up 5 stacks and pop your CD's.

To max out your dps you want to use Guardian of Ancient Kings, gather 3 holy power (intime you got 3 holy power your stacks that u gain from ur Guardian should be 15+ wich is alot of strength) You will then pop Zealotry and Inquisition since zealotry doesnt use your 3 holy power but it does requires 3 holy power to use, After that u pop ur Wings and a trinket, The trinket wich is probably the best atm is Ruthless Gladiator's Badge of Victory.

Here are some macro's that might help u in arena:
#showtooltip turn evil
/cast [@ arenapet1] Turn Evil
/cast [@ arenapet2] Turn Evil
/cast [@ arenapet3] Turn Evil
/cast [@ arenapet4] Turn Evil
/cast [@ arenapet5] Turn Evil

This will fear a random pet of a player whitout having to target it (you should have another turn evil on ur bar to fear dk's inside lichborne)

#showtooltip Rebuke
/cast [@ arena1] Rebuke
/cast [@ arena2] Rebuke
/cast [@ arena3] Rebuke
/cast [@ arena4] Rebuke
/cast [@ arena5] Rebuke
/cast Rebuke
/cast [modifier:shift, target=focus] Rebuke

This will Interrupt your nearest target inside arena, Outside arena it will interrupt ur target, and when using shift it will interrupt your focus target.
