I'm currently running a 9 str 30 agi 2H build. But I also play rageball almost to exclusion of other game types, so it really works well for that. I do miss having 24 str for far throws, but being able to catch almost everyone is really nice. Even with my armor on, I'm faster than pretty much everyone. If there are a lot of people running around naked I tend to drop my armor down so that I can still be faster than them.
One thing to keep in mind, if you play a high agi build and don't like it, play a lot of rageball and you can probably hit 31 in about 2 weeks if you are on some good teams. It's not too difficult to maintain a x5 with a good team. And no, that doesn't include stall tactics. You will make a ton of gold as well, since with a high agi build you aren't spending a ton on repairs.
