Endor Escalation Heroic Battle - Feedback

I was under the impression we would get to use pre-loaded ewoks for the event like last time, and be forced to use our own in the bonus battle. I flash farmed paploo and got my ewoks to over 200 speed and it was so insanely difficult. Couldn't beat it. After about 25 tries I gave up and switched mods back to my Haat squads. I got my face melted in round 4. I can't even imagine how tough the bonus would be.
Our guild is ranked #245 in the HAAT right now and only 1 guildmate out of 50 was able to beat it. Hope that gives a reasonable idea of how tough it is. I feel like it should be slightly nerfed and the bonus battle should be the one that's insane.
