They're ok, I wouldn't call them strong though. Only played a bit of them since I came back though Ferren focus is a lot weaker than it used to be. They have some pretty cool new champs - silent master, snowspinner, cloudwisp, windwalker were all new for me and worked out well. Ninja seems bad now.
Ninja needs to be reworked yet again, an idea for Ninjia....Here are some ideas for him trickster - 10 nora confuse - 6 nora Assassinate - 20 nora I really think ferren could use an assassinate with their swap abilities
I'm kicking **** with Ferren right now. Feel free to watch. Edit: I also think Ferren ninja's pull ability should contribute to the portal effects.
I'll post it in its own thread, because I'm honestly getting the question a lot. I'll link it here when it's up.
