While I have no use for blue keys, ultimately I will probably end up getting 100 because I never see much use in blowing cans to win these tournaments when I don’t need the rewards.
I have no problem with them making blue keys available again because I am sure a lot of players haven’t got Pete yet and would like a chance at keys (though most F2P probably won’t get a worthwhile amount of keys because someone who doesn’t need it will win the tournament, like always)
They need to have a system for turning in unwanted or extra collectibles. What do you do once you’ve got an S Class? Most don’t want a second, it’s better to move on to the next collectible. And not everyone sees use or wants a certain S Class. Why not have a permanent collection up where you exchange the items you don’t want for items you do want.
There would need to be some limitations to this though. I could see someone winning all solo events and trading in the collectibles they win for the latest S Class so there would have to be some sort of restraint. But since we are going with the shard system we need to have a use for extra collectibles.
Other games use the shard system to power up the character, this game only uses it as an access to the character. Maybe make it so that additional collectibles further power the toon or that the collectibles can be exchanged for veteran rings which further power the toon already.
