Shatterpoint?

There is a pic of my team which i used,4*Chewie and 4*Fives with gear V can stand even Mace Windu special,i just blow up him in some turn.

Mace Windu applies the Shatterpoint debuff (+100% Defense Penetration) to a character, which looks like a red version of the "Advantage" buff.

This debuff lasts for one turn, and can be removed by casting any buff on the affected character.

A list of basic tank abilities that most players should have:

• First Order Stormtrooper - The Order Relentless (self buff)
  
• Clone Wars Chewie - Defiant Roar (self buff); Wookiee Resolve (Leader, level 3, self buff on whoever procs it)
  
• Royal Guard - Imperial Phalanx (team buff)
  

You can also use Chewie's taunt if an ally has the Shatterpoint debuff with no way to cleanse it in order to prevent Mace Windu from one shotting them.

Finally, attacking the support droids will reset their turn meter, preventing them from helping Mace Windu.

Thanks Slushie, that is very helpful.
I have those exact characters, but I think I'm just too newbie for this. Even when I fend off the Shatterpoint, his basic attacks do 3k+ on my level 40 royal guard and stormtrooper and they are basically done. And they don't do enough damage to get him.
My Chewie is level 43 and decked out with good gear but it's not enough.
I am not sure it makes sense to blow 100s of training droids trying to level the other 2 from 40 to 43 when this is literally all I will use them for very soon. At some point I'll have Boba Fett and that should make this much more doable. I'll just do the Tier I thing I guess. :/

I'm guessing Mace Windu in the Tier 2 challenge is actually closer to level 50 for him to be causing you guys so much trouble but there's no way for us to tell unless someone from CG confirms it for us.

Mace, Royal guard, plo Coon, Jedi guardian and fives can auto through this on tier 2

@Slushie, I owe you a virtual beer because with your help even my limp crew (43 Chewie, 40 Guard, 40 Stormtrooper) was able to beat this on Tier II.
I had thought I needed to hit the droids to avoid the Shatterpoint thing but this was a complete waste of time that was squandering my anemic offense. I now ignore them and focus on Mace, taunting with Chewie to keep the other two alive longer and applying buffs as needed. It usually works, sometimes just barely but a win is a win. :)

Glad to hear it :)

Of course now I am stuck on the one with the two bosses with the debuffs that wear off slowly. I can do Tier I and know the right strategy for Tier II. I just don't have enough attackers high enough level to do enough damage to kill them. Not even close. Oh well, I didn't need those purple things anyway. ;)

Challenger for attacker? you just need some attacker-healer such as luminara,ahsoka to survive your whole team till the final encounter,luminara's ability block work well against those bosses.

Killing support droids give you an Advantage buff I think so you do extra damage to the two bosses.
