SEE/Wat full team can't even reach ult against no-ult Leia

Add Armorer and your chance of victory increases. If you have her that is. In TW I often use SEE, Wat, Armorer, SET, and any leftover Sith like Sidious, Dart Maul etc. as 5th. There is some rng involved, but if you manage to get tank tech and 3 stacks of beskar onto SEE, your ult is pretty much guaranteed. And occasionally you can even win the whole thing. By the time I had the ult, my 4 side toons were all defeated and I was vs 5 people (Leia, Han, Chewie, Drogan, R2) with just SEE. They had the Drogan cron, and were all at least R8. My SEE still managed to win 1v5 because he was extremely tanky with the 3 stacks and the tech. Granted I had a solid datacron on my team with like 100%-ish def, but the enemy also had a crazy cron on it so it evens out. With just Wat I would have gotten to the ult I think, but wouldn't have won for sure. But Armorer makes the battle a lot easier, unless you get very unlucky.
