Would it be gamebreaking for zed ult to ignore shields?

I go to ult a squishy as it is my job. thresh/bard uses locket. and additional shields. what am I supposed to do? be useless for 60+ seconds?'

I feel like. Fizz talon and other assassins have enough burst to kill a locket adc. zed isn't doing to well. and this buff will not affect any lanes that do not have shield. which are not that many. its just a late game buff against possibly ad carries.

as a single target ult. I think it would be fair to have it break shields and ignore them. the fact is there are way too many champions that have a shield built in+ locket. thats over 1k of effective health plus the mastery. probably more due to armor increase + heal

somehow as a zed you're supposed to go through 3k effective adc hp.

Got outplayed by a simple point and click spell/item while am normally supposed to land multiple skillshots on the target regardless of shields or not. whoop de doo. can't do anything about that.

zed ult is not

CC or AOE. or has a large base damage (zed's ult base damage is an auto attack).
