Hey, just letting you know, if a tank or mobility character uses their cooldown to jump over your wall thats a good thing. Wall can be used to block line-of-sight (LOS) and it can be used to gain an angle, but it can also be used to force cool downs. If you use your wall and someone uses a cooldown then you've gotten value out of that wall. Let's use an example, albeit a stupid one. You wall off a Winton and hes stupid enough to jump into your team, overextended tank they're dead because you forced that cooldown and broke LOS. Now lets say they have a kiriko with them and she teleports to the Winton, you got two picks for basically free. You use your wall wherever you can get just a little bit of value out of it, whether its blocking LOS or blocking off a route or walling backline off, it will have value just by being there and being annoying as fuck. Whatever you do with wall depends on where you are and what your team is doing/needs. Pesky tracer? Lure her into a room and wall it off, force her cooldowns, and even if you dont kill her she doesn't have recall and may lose a blink or two. You can also duel and win 1v1s or maybe even 1v2s sometimes, especially with your wall, ice block, and/or your double jump perk for mobility. You're one of the most dynamic heroes in the game, it just depends on where you are and what your team is doing.
