There may or may not be a slight problem incoming with more mages being able to build Archangel's

Now, as many of you know, AP itemization is receiving an update that will make the new starting items for mages (that don't build RoA) GLP, Archangel's, or Luden's. However, the fact that a bunch of champions that previously usually had to rely on Barrier now have access to another shield. I played Vel'Koz on PBE and took Archangel's and it took way longer than it probably should have to kill me, granted they were able to before I lured them into my team, and I won trades that I wouldn't have on live. I didn't need a support to shield me in team fights, I could make my own shields with blackjack and hookers. Maybe this is a good thing, considering all mages have got in the way of defense now are Zhonya's and Banshee's, but I thought I'd warn you. I'm not saying mages are going to become unkillable, but it might not be good for one reason or another. I don't pretend to be an expert on this kind of thing, but it did raise a red flag.
