Tanks with Devourer

I dunno if anyone else has noticed, but tanks with devourer are kind of ridiculous. Once sated, it gives you plenty of damage without building a single other damage item. And you're free to dish out as many autos as possible considering no one is going to focus you.

are the ones I've seen go full tank.

EDIT: Tried Rammus three times now:

First game I went 4/1/7, had devourer at 8:13, and sated it at 15:32. Was a win.

Second game I went 11/10/8, had devourer at 9:05, and sated at 20:15. Was a loss.

And finally, third game I went 8/6/19, got devourer at 7:24, and sated at 14:11. Was a win.

If you can get control over herald and drag, it really isn't hard to get sated on any champion, and Rammus's clears are not nearly as bad as people make them out to be.
