I’d be down for -1 sec on repair pack, since removing her armor overheal will inevitably make her waste some of the pack’s value. But that’s about it.
I think the shield changes compensate themselves as is. Don’t forget that you don’t have to let the shield break, and you now have an additional 50 hp cushion to make sure that happens as little as possible. It can be a net nerf for sustained fights, but a net buff in 1v1s.
