I ended up with enough green dragon shards after finishing my ratkiller to tier 3 that I ended up making a second hat.
I agree with a lot of what you are saying and I know there are times where I flat out would not need perform and wouldn't want to switch to my dagger (and do not have quicken on).
So after last night I have 2 fully upgraded hats. Seeker 6 Perform 15 and Seeker 6 Concentration 15. I ended up filling the haste IV and 35% more coins as well.
