No need for caps.
Aegis is still the best tool. It will probably have floored blocking against new delve NMs, but to be practical, paladins don't really get to fight NMs, but shield-swapping is a thing (whether it be Ochain/Aegis or Killedar/Aegis).
The thing people aren't understanding is that shield skill does influence ochain's blocking and that anything that requires 650~ shield skill might really hurt Ochain. It might not, it's tough to say. New fodder could even be high-level.
The only ones that know at the moment is SE, and that's why I'm asking them.
If I need to have a Killedar, I'll have one, but just like all the other RME owners, I want my time invested into them to matter.
