RR/GH/Apoc is almost always the best atma combo.
Apoc is better in this order TripAtt > RR3 > instaCast.
Add all that together and Apoc is very nice for NIN because we will die at some point, being able to RR > 2Hr > RR without weakness is useful. RR also useful When lowmanning things which a lot of people do these days.
InstaCast is always nice when you get a free set of shadows, If SE added a JA that let NIN cast next spell instantly without recast would anyone really complain or not use it?
TripAtt obviously because well 15% is nice as well as more aftermath procs and able to tripAtt on Blade: Hi.
This is not a bad option, I understand why SE doesnt overwrite NI however a check sum to look for <3 shadows really isnt that hard. It is however not a big issue considering other bugs/fixes that are more important.
I would like to see this happen however it really isnt a huge deal just remove buff before you cast it if in Abyssea.
I really hope SE doesnt listen to posts like this. That is a horrid idea, InstaCast is nice for anyone that uses any form of spell casting. If it bothers you that much then dont use the atma but dont make the rest of us that like it as is suffer.
