To test things I did two things now:
I sent 0.5 TRC to BTC-E on the old address that I use for a while now.
Then I generated a new address in BTC-E and sent another 0.5 TRC.
All for the sake of science

Now wait if they show up @ BTC-E... If they don't it's borked?
unless btc-e simply stops polling the old funding address, once a new one was generated?
