Hope is the only shield with this problem, but therefor its immaterial. And only 2 or 3 (upped/unupped) creatures make Hope strong enough for its quanta costs. Also the problems are rather Firestorm, Thunderstorm, FireShield and Spin Carapace than any single spell considering that you will probably play Hope with a deck using Fractals. Furthermore nobody will waste all his single spells destroying RoL´s if there are still stronger creature on the field. In addition you can biolum. Dragons and other creatures that arent fragile. I wouldnt consider "not vulnerable to creature control" as an plus factor at all.
