It depends on what you are doing with your bike.
For daily commute on pavement there not a problem at all. You just have an annoying diving when you're hitting the front brake.
For doing some mild offroad and back road sections just put some progressive springs in them. That's what I'm planning on doing next spring. some hyperpro will cost like 150€ and the diving will go away.
for some serious off road stuff you'll probably want some adjustable ones.
