I'm done with this event too. It was long but less boring and painful than expected. Missions are shorts (well, as long as you don't face thoses horrible healing worms) and the random order make it funny. Even if it's the same bunch of stages grinded again and again, it's more varied and far less boring than regular event grinding. That was a good thing.
The other good thing is the utility of healing panels. After all this time, it became usable with an actual and decisive purpose. That was a great idea. First time ever I play healing panels indead of Solar panel.
Like Volarmis said, RRose did everything against Earthworm and saved all Spring Garden. She really deserve her name and her 6th star. I wand to add a very special mention to Kerria, RGPinkladies, Saffron, Camelia and Maid Cowslip (espacially Maid Cowslip for doing her best aside these monsters) for doing the whole event alone. Three times. I never enjoyed this team that much.
Now, the event is goind to end and we will be back to our regular FKG stuff without trouble. That's a bit sad. I really liked this special event as I liked Nidhogg the first time it came, despite my first thoughts on it on first half.

Definitly one of my favorite event with first Nidhogg, first Nae event and RRose event.


edit: Ah, and f*ck thoses super tanky beetle of hell just above. Certainly the worst things here, just before the final boss itself. I hate thoses guys.
