Good thing LTC difficulty is dropping again, it might still be a good time to reinvest in extra shares for the shares multiplication that is coming up at the end of this year!

I was not looking at the static difficulty that changes every +/- 3 days but the current total Litecoin network (1379 Ghash atm) which has decreased significantly compared to yesterday. Good thing you are mentioning though, I was not specific enough
It can't drop, my friend
. Look at the hashrate which was pumped into network last few weeks because of "who-knows-who".
