I've used AP a lot. I do mean a lot.
I have used it to solo most LOLNOPE bosses, like Colossal Primarch, Mutated Void Dragon, Undead Raxgore, Chaos Lord Ultra Alteon.
It's excellent. Especially against Undead with the Commandment getting the bonus damage against Undead, and SM:E having a chance to 3s stun Undead.
It's a fun, versatile class. Right now full lucky works great, likely Hybrid will be the enhancements for it come the rewrite.
Also, for farming, it now has maxed range and mixing Commandment with SM:E is great.
