@Etjama thanks for the tip, I'll be looking forward to go with Elsa or longshot as I use them most of the times in act 5. I got vision aarkus last month but I just ranked him up and I already had a lot of tier 4 cosmic catalysts so probably after I'm done with Elsa or longshot I'll be able to rank him. At the moment I haven't been using thing a lot but yes , he's a good defender and he's fun to use so I'll be thinking about him later on.
