Possible looting issue (friend trading bias?)

Having an issue where most of my uniques/harbinger loot is focused around minions. I played with a friend through campaign and traded him a few minion based items early in the game (while he was still playing) and ever since the loot has been fairly bias toward minion based gear. Not sure if anyone else has noticed this since loot is all “RNG” but on my previous playthroughs it does seem to have an idea on what you are trying to build around or play with and will try to support you on your way. Anyway just something to look into if possible.
