Yay. A cash shop-based holiday. How... expected. Yes, I know you can buy gems with gold (not an option for most people now) and you get keys from the Personal Story, but those aren't available in anywhere near the quantity needed to remove its status as a cash shop holiday event.
I am curious, do you truely believe these statements when you make them? I mean let see..
Cash shop content is 2 costumes, 3 minipets, 4 weapon skins, a few shoulders
Non cash shop content: Jumping puzzles, a bunch of achievements, 3 weapons, 2 rune types, 4 different acts of story, costume brawl (which you can do without having to buy the costume), trick or treat bags, candy corn, halloween style food, multiple temporary transformations, decorations in multiple zones, other craftable stuff / secrets that are yet to be discover. And thats just Act1 out of 4.
Yeah you're right definitely a cash shop only event.
Tons of stuff and all you see are the chests! hmmm
