This game just needs more content, but shortening the timers are not going to help. People will get more bored at leves and people will start doing leves all day.

There's no fatigue anymore so you can grind all you like now without SP penalty and that is very good. I only did levelink PTs for about 10 ranks, PTs were hard to find because my timezone sucks sometimes. So I grind. And most of the time solo (which ain't that fun).
