The first game I played as of the season 3 patch was great, but one thing I noticed is that my team had multiple people buying the Captain boot enchant. It turned out it was not because we all wanted it but because it was not really obvious that more than one of us had it. To me it seems less useful for multiple people on one team to get it and I think one solution would be to add the chat emote that says "so and so has purchased [insert aura item]" whenever someone buys the Captain enchant.

For all I know it might be a bug that it does not already do this, or if anyone else thinks similarly to me on this, but I figured I would add my two cents and see how it goes.

It can be useful with two people, though. On backline support to help teams withdraw, and initiators to let their team follow up better.
