Thrawn with a zader lead for squad arena?

I play zader lead and thrawn is wonderfoul

I wouldn't spend on a Z Vader Zeta because he's on the way out of being viable at top levels, and in case you do, sub kylo and get thrawn and sith assassin in there

If your shard is Light-side team heavy, Vader is great with a fast SA / fast Thrawn against Chaze / Rex / R2 / GK ...once you get it tuned and have the speed humming you can blow them off the field with SA / Vader / Thrawn / EP / DN / Tarkin / DT combos

The problem with Vader is Thrawn leads and also Tarkin leads - Tarkin can outspeed Vader and pin him pretty good and Thrawn leads vs. zDV is beyond ridiculous. I used zDV as my lead exclusively after R2 was released up until a few days after Thrawn's event ended. DS teams though, and Vader especially, you need some solid speed mods to really make it work.
