Why is there no NL Omaha?

[DougI]

My friends and I recently started playing Omaha to mix it up.
However, from looking at one or two internet sites, it doesn't appear that anyone plays Omaha in a NL format.
Can someone explain why this is so? or confirm whether NL Omaha does exist to some capacity at certain sites or B&M places?

I can only imagine that NL Omaha is non-existant because the game would get too out of control and strategy would go out the door, in favor of gambling on most hands.
