With Sanctity Aura up, hammers of wrath turn into the biggest boom for your buck in the game at this point correct? 1 Resource 5 Damage?
Consectrating for 4 Damage across the board generally solves any rush issues. Skullflame shield a great answer to the loss of Ret Aura, I prefer the new mag shield though.
Against the big solo monsters you're going to need some equipment removal which just isn't something paladins are awesome at solo. With paladin I just don't see running solo. There's potential for boom here, but not enough answers for everything minus allies.
Cudgel is by far one of the scarier things to come upside my head in a tournament of late. Coupled with a seal of the Martyr you can keep the ally rush coming aye. I prefer seal of command if you're already running Ret though. Now you swing for 5, and deal another 4 holy assuming you're using the Cudgel. And should they exhaust (Not that you can't exhaust them) or one of their allies comes out that needs answering, 6 Damage for 1 resource with the delicious aura still out...
We're talking about a turn that should you Hammer of Justice, Beat them upside the head with the cudgel+Command, then Sac Command, 15 damage, for 5 Damage, which is alright for a finisher, but the wraths are what tie the wrap the whole thing up in my book.
Unpreventable 5 Damage for 1 Mana with the aura up is worth tears if that does stack correctly. Instant...Instant...I need a towel.
