Sure, there are some assassins ( Mercury, Serqet and Ne Zha) and some hunters ( Jing Wei, Artemis and some other few) that benefit from crit items/builds, but crit isn’t always the best choice, even for these gods.
I can’t understand the NEED some people have to build crit on EVERY ******* PHYSICAL GOD! No, Neith doesn’t work with crit, and Nemesis doesn’t either. And don’t get me started about Loki.
Am I wrong thinking like this? Is crit always viable for some gods? When sould I build crit and when should I build penetration?
For Mercury, I would disagree. Crit on Mercury is essential. You will almost always build crit.
"No, Neith doesn’t work with crit" - actually she can, it's just not optimal for her and other hunters can do it better, especially as ability based hunters fall off lategame. Nemesis can work with crit but again not great on her. Of course crit on Loki is a terrible idea.
As Mercury you want crit in 90% of your games. I've seen 1 or 2 pros go a more bruiser build on him with perhaps 1 crit item like Rage (think it was CaptainTwig) but thats about it.
Oh, and you should always build penetration: what type you build after flat pen depends on the god/goddess you're playing: assassins tend to go with Void Shield while hunters use either The Executioner or Titan's Bane.
I guess people become fascinated when they see that 500 critical hit appearing in their screen :v
