Brand's passive has a large impact but has no indication. (QoL suggestion)

In a 1v1 situation, this isn't a problem, but in a team fight, when you have Brand's ult adding stacks on its own to multiple people and passive procs spreading stacks over a large AoE, it's impossible to keep track of who has how many stacks, whether you're the one in the midst of the explosions and are trying to avoid exploding yourself, or you're Brand and you have no idea if you'll need to use one ability or two to finish procing passive against someone who was in the collateral.

We see indicators for many similarly impactful mechanics such as P, P, E, W, P, P. Brand's passive counter takes place behind the scenes, only visible on the tiny debuff bar. It feels out of date simply because it doesn't have the indication we've come to expect from similar mechanics.

TL;DR: There should be a way for everyone to see how many stacks of Brand's passive someone has by looking at their champion. Teamfights are messy and this is information you need at a glance.
