Yeah, it definitely isn't something I'd recommend for people who don't know what they are doing. It's feature set is more comparable to enterprise hardware like Cisco or Juniper. Their terminal configuration utilities are pretty easy to use, but I actually really like their webui. It exposes all the functionality (which is a daunting amount) but is clean and very responsive.

That said, RouterOS pretty well documented and isn't hard as long as you know the basics. Mikrotik actually has a pretty vibrant little community around their wiki.
