Maybe a problem with shields is the ease that they're applied
Think about it. Who in the game has a shield that is a skillshot?
Well we got
and uhhhhh
lantern technically and...... Yup
Meanwhile for point and click shields we have

Also have a few less-than-point-and-click shields
"Be near something"

"Just because"

And a few unique cases

Anyone seeing a problem here? Why don't we get to a point where we have more unique cases and skillshots than point and click? This overlaps into healing as well. Maybe shielding feels so bad because there is no way of playing around it other than hoping they waste it or have awful reaction time.
Shields are just too easy to use for how impactful they are. Can we work on that?
