Well, a lot of gaming companies have a tendency to force you to play through their preferred method of matchmaking. It is somewhat understandable because it allows them to block illegal copies from online gaming, for example, but as with most other anti-piracy stuff, it is more of a nuissance for people who have a legal copy than for the warez-guys.
DirectIP is a must for online leagues, anything else is just too much of a hassle. And while I quit my online leagues a while back, I still hope for their sake that DirectIP connecting is in.
