Cheers man, appreciated! I did end up top 1%
Towards the end I moved back to top 5% while still having 5 flags to use, so I had to give it a try. I won the first 2 battles, which were very very hard and had luck with the shields falling my way. Third one I lost, since it was only 5 hours left and only 2 more flags I decided to give it a shot.
From day 1 my defense grade had been A.
My loot, I have to admit that I was a bit disappointed with not getting any ascension mats, especially good gloves which have been avoiding me for months (upside is a got a lot of mat now).
