Existing barriers would be debuffed.
Existing cooldowns don’t get debuffed.
However cooldowns don’t get better if the debuff is removed until the cooldown refreshes.
The idea looks great even a bit complicated on the paper. In the heat of action either for players or spectators I expect some confusions about why the barrier gained health or would lead to an overbuff of barriers when Sigma and Rein would just have to time it correctly in order not to feel the nerf at all.
Although, I like the idea and it’s typically the kind of things I’d like to see one the experimental card to test how it actually turns out !
But this is on a healer, and it’s a MASSIVE survivability buff to said healer.
It doesn’t do anything for her team since she only has it for personal use, it’d just turn her into a walking paladin and make it impossible for heroes like Genji or Tracer to do their job.
And that’s fine but barriers are a team thing. Synergy comes from the barrier utility and that comes with amount of value it gives with time.
This is why symms og 25 barrier was kind of irrelevant. Because it was very nice and didn’t add to overall team time. But rather individual player time.
Imo brig also needs a shield need because it shouldn’t be able to block beyond an initial burst. Tank barriers should be 1000 and below and instead their value needs to come elsewhere.
Also, I do think the ttk is something they want up. So lower shields ties into lower heals. Where imo, Ana heals need a Nerf but…God forbid that happen anytime soon.
But this as seen, is already the case for orisa sigma. The difference between orisa rein, is that rein wasn’t brought down with the rest . Orisa Winston isn’t really a huge thing
This always ends up boiling down to “I would like these tanks to go back to being overpowered” and then trying to make some arbitrary limits on usage of the OP heroes. No. Barriers were universally nerfed for very good reason. The game has only improved since those nerfs.
Somehow I’m interpretting this as
“I like the meta as it is, even if it has limited variety of competitive barrier tank choices, because a variety of competitive barrier tank choices is not important or desirable”.
There is more variety in tank choice at the highest level than there has been for like a year, because the meta tank choices aren’t ludicrously overpowered and are simply meta so you’re not mega-throwing by choosing anything else. Orisa and Sigma being gone also removed the boots the tank role had on the throats of the other two roles and also opened up ability to use a lot more of each map.
Literally the only two tanks that got worse were Orisa and Sigma, and wow is the game improved by them not being universally present. We can have more variety in barrier choices when those barrier choices don’t also have every other advantage as well as the best barriers.
Pretty much all the comments here are focusing on what we have now, but what about the future? We can’t have two-to-four barrier tanks (depending on how loose you are about the definition of “barrier tank”) from now until the end of time. There’s going to be another one added to the game at some point, and what then - have that one relevant for a while before going back to Reinhardt, Reinhardt, Reinhardt?
Outside of composition restrictions like 132 and one-barrier-per-team, I don’t see any way of fixing the problem of barrier tank stacking outside of something like the OP’s suggestion, or redefining how barriers work (for example, most barriers inconvenience their own team in some way, or don’t absorb 100% damage).
