@Luxxtenebri While i agree with a majority of that and that blocking with the shield should be a skill there is still a few flaws with that. I have played a few other BRs and while glad Apex has these shields, again sometimes it really isn't worth it with how easily they can be exploited.
1. Mastiff, someone has that you're dead. As players can easily psyche each other out with direction. Before that it was the same with the peacekeeper and it still kinda is.
2. You're slower while the shield is up so you'd need to drop it for a few seconds to try and turn fast enough but that also leaves you completely vulnerable at the same time.
3. As you mentioned 'thirsting'. While i can't disagree that it is useful the shield really isn't a deterrent for it, finishers just ignore it granted it does take a while and can be interrupted... worst case is still getting separated from your team and being finished while the rest of your team is pressured away/downed as well. Best case lone enemy tries to finish you but teammate(s) save you.
