Anybody run CLS, R2, Solo, Leia, Cassian? Or CLS, R2, Solo, Old Ben, Cassian?

Ive ran with cassian in a similar line up, he gets the job done but i think you have better options. Your biggest need is a solid tank in your line-up imho. If GK isnt in your near future I would consider gearing up Chaze and swapping Wiggs out. There are CLS, R2, Han, Chaze teams in my shard that compete for 1st. In the near term you can try swapping wiggs out for sthan/ob and leia.
