Old Ben is useless!

Dooku phasma Rex I even see HK more than ben in my shard, I understand that is leader is ok, but is that worth wasting a space for just leader ability? There are what 10 other toon with ability block. I use him in my last arena fight to help keep place but I target him in arena. It's a 4 on 5 then.

And please if you don't have him don't give your opinion, I'm not trying to be mean but how could you know.
