Is zMaul still viable ?

Yes.
#1 w/ him.

It depends on your other heroes. I'd say that with a very fast Sass and possibly Zavage, he could turn out to be handy.

Yes. The proliferation of R2 is making it tougher on Zaul squads, but they're not dead yet.

zMaul Sith teams are still viable, but depending on your shard they may not hold very well.

Hey, that's my team!

Having DN / SiT (or GK) / Zavage (lol this guy) and of course, your main carry, the one and only, Sith Assassin, will make your Maul team not just viable but #1 capable. Offense is pretty easy with multiple teams honestly, this game's AI is pretty bad. R2's existence and Rex makes your Zaul team more beatable than before, but not outright invalidated.

I hover around rank 20 with Zaul, Zylo, SA, Palp + Nihilus. I can't beat Rex+Chaze teams with any kind of power difference, but I can still beat ones at the same power level. R2 is NOT fun for me however. I do well on defence too, rarely dropping more than 5-10 places.

It's completely shard dependant. On mine there's about 8 left in top 50 as many now have GK or R2 and running Rex leads. On the new shards where there's no R2 or GK he's ruling still.

They can still get top 10. R2 has effectively neutered Maul teams so Maul teams fall a lot farther than they used to.

Running zMaul with Palp, Sass, Zavage and DN and it works really well against Rex, Jedi and Rebel teams as well as DN lead.

R2 is making a little dent but overall not that much

Depends on your shard. If it's full of Rex teams, well good luck.
