The fact that it was difficult made it brilliant. After 48 months of playing, I can honestly say it was the greatest, most exciting event I have ever done in all of my playtime. My team had few troubles actually. We were randomly thrown together, and we did amazing, but it wasn't easy, and that balance made for a great experience. The entire task force, and our mystery man's new letter were so enticing and got me into the back-story immensely. This task force needs no tweaking on difficulty standards, the mass amounts of enemies and the vast armies make it the most realistic feeling event/task force I have ever done. Sure it's frustrating, but on the final fight, we had a few deaths, and it didn't take us long to overcome the nictus essences. Just get a good team

I think a key would be getting a good stone brute though, and a good empathy. Thats it. This is the closest thing to the perfect task force in my opinion. Devs, you have thoroughly impressed and pleased this paying player.
Now, Please, leave it as is! Leave this something actually difficult, make this something you HAVE to work for! If it's too hard for so me, then tough luck, try again later, it'll work out eventually, it worked out the FIRST time for me, with a random pick up team.
This task force takes leadership, coordination, someone to call targets, and for everyone to do their role, and do it well. The fact that you can't just pick this up and blaze it in an hour is what makes it so golden. I truly hope with all of my heart that they leave this task force the way it is, nigh perfect.
