It would be awesome if there was a talent (or just a general feature) to manage your shields.
I.e. As i understand, the current order of shield-checks is:
1: time shield
2: damage shield (including Barrier and all Runes)
3: displacement shield
4: disruption shield
Meaning, if you have a sustained displacement shield AND a damage shield the displacement shield won't be checked until your damage shield is reduced to nothing.
I don't know if the reason for this is lore-specific, or if it's just something that's not seen as important. But when running around as a fragile archmage it's rather important.
the talent would be a talent like the "communicate with golem" or "command staff" type of talent, OR just a sub-menu somewhere.
This feels like a great addition to all the fragile classes out there

Also, all credit for what i know is from this "shield managing" article found in the te4 wiki:
