My feedback will mostly mirror that of others here, but perhaps repetition is what you want to hear.
To begin with, farming BNY is getting a bit old. I wouldn't mind having to do it the 5 times required to get the badge, but I have around 90 toons, and each year I only get thru so many trying to pick up all the badges and such, that still not even half of them are done.
Candy canes should drop (small percentage chance if you like) off snowmen. It's very little effort for a higher lvl toon to kill the snowmen they spawn while present hunting. The work of a few seconds in most cases, but many don't bother because they have no incentive to do so. Provide that for them.
I'll join with the others in my opinion of the ski slopes. For those that like them and want others to know of their prowess, provide some sort of bragging rights. Maybe zone announcements or something, but not badges. I love badges, and I'm unable to get anywhere near a gold, which leaves me feeling a bit ill. Lower the required times or allow us to purchase the badges.
Now allow me my rant about halos. I love the idea of halos. I have a couple of demon toons and one angel. Problem is that they are all well below 30 and given my extreme case of altaholism I won't be seeing 30 in all likelihood before next Christmas, or later.
I don't believe halos should be auras at all. They either belong under hats (assuming you can fix the hair issue) or under Head Detail 1. Why should I get screwed out of using a regular aura when I finally do hit 30? I had my angel's 'heavenly aura' already picked out in my head and now I'll have to decide between that and a halo. Not fair. Put em under Head Detail 1 and you solve all the problems people seem to have with them.
As fun suggestions, perhaps you could have it snow outside. That would be nice. Don't cities usually string up lights and holiday decorations on buildings and lamp posts? Really get us into the holiday mood.
Perhaps you could have random sightings of Santa and his sleigh in the skies over Paragon City.
Random ice throughout the city could be fun as well. Like the ramps and ice found throughout the Frostfire mission.
A giant Christmas tree in AP would be nice. With a skating rink. And holiday music being played over a nearby speaker. You could use one of the parking lots around City Hall. And maybe turn one of the main drags in AP into a speed skating course. Not for prizes or anything, but just for fun. A nice mile long street you can skid up and down to your heart's content.
Well that about does it for me. Thanks for the thread. Again goes to show how much you guys care about what we think. Happy Holidays!
