Guild Wars 2

This won’t happen. They restricted engineers and elementalists to 1 weapon set for a reason… Elementalists have their attunements and engineers weapon kits giving them plenty of skills.

Welp the title says it all.
Step 1. Grab a riding broom, possibly an environmental item which can only be used at the minigame place.
Step 2. Ride the broom hitting swiftness-giving spots, jumping over obstacles (for example tree logs and holes in the ground, which would teleport you maybe over the obstacle and then you’d accelerate to full speed a little while for that disadvantage effect) and avoiding all kinds of crippling, chilling and even immobilizing things!
Step 3. Win… or lose, whichever you’d prefer!
Step 4. ???
Step 5. Profit! Collect your reward whatever it might be and enjoy! It might be your very own Riding Broom, a Witch’s Hat or even the whole costume? Or maybe some other Halloween themed items?
Or how about this: All minigames give the same tokens as rewards that can be used to buy even more awesome stuff? That way minigames would get the attention they deserve.
