A friendly reminder for Night Stalkers

Given that NS is being picked very often nowadays for his extreme ganking power, I'm seeing a lot of players pick him and forget one of the most fundamental strategies: As soon as nighttime hits, POP YOUR ULTIMATE, and continue to use it as soon as it is up. The only time you should not use your ultimate when it is nighttime is when there are fewer seconds left of night than your ultimate CD minus your ultimate duration (155/100/40 seconds).

The reason you should do this is simple. You don't use it during the day time until you need it, because you could get ganked and desperately need it, and it will be on CD. But at night, if you use it, not only does it extend the night, it will come back up during the night, so you will never regret not saving it.

TL;DR Night Stalker should ALWAYS use his ultimate as soon as possible during the night (except the exception given above).
