@Riot Testers: Can you guys experiment with this idea for a change to Barrier?

Have you ever felt like Barrier just sucks balls in mid-to-late game because you have no resists to back it up, or the enemy has too much damage for resists to matter? Additionally, Barrier always seems to get crowded out by etc., because all those options are generally more useful.

I think Barrier needs to be upgraded, but in a meaningful way. To that end, I suggest the following:

#Barrier Shields your Champion, absorbing up to X damage. This shield decays over 2 seconds.

In this variation, the shield strength would be MUCH higher than the live value, but as a catch you need to time it PERFECTLY to get the most out of it. Time it too early and you lose a lot of potency. Time it too late and... you get the idea.

At the very least, can Riot run some tests with this variation and see what they think about it? If it doesn't work, tell us why/
