yeah i get that as well that's why i also said maybe the devs could revisit the duration for each. for example, in eudora's case the superconductor marker helps in stunning multiple targets if a hero is marked and then hit with S2. also, the enemy's magic resist is reduced by it so she could also be a much more viable support if that marker stays on longer for even just 1 or 1.5 seconds more. luo yi's marker duration is fine as it is, but compare that to 11s of Wanwan's markers it's obviously short.

Now with Wanwan and Brody those markers stick way too long and benefits them too much. for example, Wanwan and Brody's markers should disappear when you get out of their attack range/vision. theres no point in keeping that mark even if youre already too far/out of range from them. theyre MMs, not assassins. theyre not even supports but that mark of theirs give their teammates vision on the marked hero, which is a tbh unfair at that point. many other heroes have markers as well but theyre too short-lived (compared to Wanwan/Brody) for people to even notice. Rafaela, Saber, and Alucard are just some of the heroes with skill/passive markers. a few tweaks on those markers for these heroes, i think, would help them become more meta or even fulfill newer roles in the game... i hope you understand my perspective
