I pumped my fees, too, for a simple reason: competition.
It burns 1000 Coins to be a validator. Validators, that get their 1000 coins back, fast, get into a position, where they can lower the fees dramatically. So for earning back the 1000, I have to keep the fees up a bit, but my validator is no longer attractive... so for now, I keep the fees a bit higher, get the 1000 coins back and will lower the fees to a low amount
This is, I think, the right move.
If you're thinking about starting a pool, take note.. At present, there's room for you to get in, pay off your burn, and drop with the herd as time goes on.
Later, it will be much more difficult to start a pool. There's still plenty of room for more pools, many of the current ones are overweight votewise, so getting votes isn't going to be a problem.
