I`ll chime in a little bit as far as the 60% chance to strike again goes.

I have the non promoted Protea and she has just 40% and that already made a difference bunch of times. To get 60% - you gonna feel it. Thats for sure.
I think evolved Iono has what... 40 ? ... wait it seems she got buffed in this update, although I am not sure what type of buff it is.
Anyway Promoted Protea has higher chance than an original 6* and by a lot, so she will make the difference.

Personally I think they are overdoing the promotion a bit too much. Bunch of the promo girls are better than native 6* and at that point the incentive to get an actual 6* drops massively. If they were buffed to pseudo Rainbow, or a proper but weaker rainbow I wouldnt mind this as much, but more often than not, they outscale the original 6*, sometimes by a lot.

Wutan - gratz on the pull you lucky mofu you ! This time the girls in the gacha are n1.
I really like the art style of the new Magic Pickerel Weed 5*. The hammer chan is pretty decent to, and I really like the copy > paste > recollored event girl. 6* seems cute enough, though my personal favorite this time is Pickerel Weed.
Maybe I`ll try one big pull to see if I can get her.
