I feel like queen got a huge nerf due to the sheild being visable. Before the enemy would accidently waste a spell on her sheild...but now they wait for it to poof away.
Yes i know...people will say just keep it up blah blah blah. You can always keep it up, and part of the strat was trying to guess who the enemy would target. Now that everyone can see who has sheild queen is much MUCh weaker.
