Somehow Riot have to stop that B Long plant and spam Meta in Pearl...
They can block one side of B long i mean B entrance box(players are too much jiggle peeking from that spot)
Alternate fix: Nerf duration of all Viper and Harbor util. Since their walls can block the largest area, they shouldn't last as long as traditional smokes
I feel like his E should still be shorter since you can custom bend it to create any angle you want. On Pearl EG were using it to cover every choke on both sites and it lasts long enough that they could use it to fake one site while they walked to the other.
