It's probably better if Segwit is activated. The amount of people using Litecoin is going down all the time. Will soon remain as another dumped altcoin. 
Why do you say that? Do you think the users will come back because of segwit and then later the Lighting network? Please state your reasons why you think that.
It comes back to my main question why segwit is necessary in litecoin. Most of the arguments made here are all speculative and made up by unqualified people who want to make themselves look smart.
1. bitcoin scaling problem
2. litecoin is on all, or soon on all exchanges
3. litecoin is one of top alts that have fair distribution with no premine, instamine and shady works of the ppl behind it
4. litecoin code is almost copy of bitcoin so dev that work on segwit, LN, etc will be happy to work on litecoin too
To the math yourself, market is mad due high bitcoin fees and slow trasactions, they don`t want BTC clone, they want scalibility solution as segwit!
That is still very speculative. It does not guarantee the same bitcoin sized success for litecoin. From my view all litecoin did was to take advantage of bitcoin's bad situation. If their development team have thought of doing segwit first then things would be better, but it did not.
What if segwit activates in bitcoin? What will happen to litecoin now? It shows that the move to litecoin is mostly speculations by the traders. If a majority of merchants started to accept litecoin then I would be the first to say litecoin is gaining.
