So, I saw somewhere that Iron Spidy didn't fit the pattern of who should be the featured characters in the shield training event.  Who should have been next, more importantly, who do you think will be featured  in the next shield training event?  Who should I spend my iso / favorite designation on to get them to level 209 now, rather than scramble to make up the covers when the training is up?
