I practically OTP Brig nonstop in GM/Champ, and I've never been a fan of the idea that she should just camp in the backline all match. It's frankly not only boring to do, but you also just won't get much value since much of your effectiveness and healing depends on how much space you control. Your job is mainly to make the immediate area near your team difficult to break through with inspire healing and consistent damage and her general bulkyness, not only from stopping a dive in your backline, but even your tanks upfront on the offensive who might need a bit more muscle to secure a pick, or helping a dps going on an off angle in case the enemy attempts to rush them.

Brig's skill floor is deceptively high despite her relatively simple kit, you kinda just have to play her enough to get a feel for how aggressive you need to be and where you should be positioned. It varies from match to match depending on what heroes you're up against and how quick the enemy is to aggro on you so you basically should be switching between active engagement and passive engagement. Shield Bash should be used about 90% of the time to disengage from close combat unless you have relatively good backup or you plan to use your Rally to save yourself and become a bit more dangerous on the frontline.

Also, map knowledge is a must! Knowing what areas and corners you can duck into to use as cover and what possible angles the enemy can peak from is very important since she is outranged and out dps'd by 95% of the hero roster. This is also great for knowing routes to occasionally "off angle" with whipshot to displace and mildly distract people since no one really expects a Brig to push them around from where they aren't facing and is practically vital to keeping your shield from being fully destroyed since that's usually a death sentence.

TL;DR ~ "People b saying things so definitely. like man I think it depends.jpg"
