The first time I got bored, I created a new character and started from scratch. You could try this on a different server, and meet new people.

I recently left my FC for many reasons, one of them being that it had grown quite stagnant to me, being a lone wolf and picking up a couple new LS doing the relic grind has been refreshing.

You can try soloing different content, but this only works in the short term. A Whm in my old FC used to duo everything, so that could kill some time.

The game is honestly at a very stagnate point though, and I think many are in the same boat as you. It should get a little better as 3.0 progresses, but it will happen again at 4.0. But maybe the game needs a drop off of players for SE to losen up the purse strings. Of course thats a gamble.

You could take a break, but I know for me at least breaks become permanent vacations.
