Yes, you are right, Samurai needs to be addressed. It's basically dead now. No clue why the Devs didn't plan on it earlier - but SE works in mysterious ways.

But two things:

a) Most of the ones who request meta (even clear groups, lel) are just reddit sheeps who don't know what they are talking about.
Only the top 95% of the playerbase knows how to make use of meta. This was many times discussed in the Balance Discord, and it is very true.

b) I main SAM still and didn't switch like the Hipsters to MNK, but I was able to clear o5s-o7s with pugs so far. It was hell, high purple and orange parses don't come easy with bad pugs, hence why I decided to recruit.
My advice: Just avoid the meta monkeys, avoid the salty idiots, make your own static and surround yourself with likeminded people.

After all, we are all here to have fun, but a lot seem to forget that. Just don't give a **** like me.
