I'm not sure if this is a bug or intended, but it seemed off, so I'm reporting it just in case.
If you buy the wrong trinket at the beginning of the game, then refund the trinket and buy the correct one, it goes on the full cooldown instead of the several second cooldown that you normally get at the beginning of the game. This happens if you trade the trinket for a new one, or press the refund button and buy a new one.
Its in place because they don't want people to get a fully/partially cooled trinket every time they split. Its easy to abuse. I don't think that it would be an issue if they removed that issue for the first 2 minutes of the game or just when you use the refund tool.
It's in place for a reason. It's not really that abusable or practical to abuse, but it still is there.
Let's say you're defending a siege at in your base, you could place a ward on the other side of the wall so you have vision, right? Then you get chunked or something and need to go back. If you trinkets refreshed, then you could swap out to the sweeper and clear any wards they may have placed in your base.
