Idea for a Champion Trade Hall
Now before you all start getting on me that Plarium wants you to grind or buy shards so that their numbers look good on paper and that they make money from you, I know that already but I figured i would pass along this idea i had, honestly not sure if anyone else has suggested something like this either since I wasn't going to go through all the pages on this forum.
Since their is so much extra space around the Bastion, that they could turn them into other locations to use for things in game, that they could add a Champion Trading Hall. It could be a feature that lets you always have the campfire active since its not used unless its a special event like christmas.
Basically what it would do it a player can post a champ that they have, that they do not want because it's a dupe or because they have better already, for trade and along with it post a list of champs that they would want to get for it, or champs that they just want in general. Once another player wants to trade with you an and you go to the trade hall, it will give you an option to accept or decline depending if you agree with the trade or not.
There could be filters for champs you have and champs you want that allows you to search for possible trades. Also if a person posts in a chat channel that they are trading, you could click on their name and it would give you an option to go straight to the trading hall, kind of like when you go to do daily quests, you can click the box and go straight to what you need to do.
