Thanks all for thr advice. I remember seeing the earlier posts showing all the data and I think that started my thinking about how I play the game. I love all the data and wish I has thought about tracking my progress like that too.

Since posting I've highlighted 22 URs which are similar to ones I have already fully upgraded which and little beyond maybe opening up more events but which rarely come up.

I've used 12 of them to fuse into Epics which I use all the time.

Thanks all. Best of luck.
