Braum V Yasuo, a discussion on sheilds.

so, i have a decent number of games logged on both and i was wanting to know the ins and outs behind the thoughts into both projectile blocking abilities!

for comparison

• ability can be re positioned
• blocks full damage of first projectile from direction the ability is facing
• all subsequent projectiles from direction ability is facing hit caster for mitigated damage
• intercepted CC is transferred to caster
• caster ignores unit collision while active
• caster gains 10% movement speed while active
• duration 3 seconds scaling to 4 seconds

• placed flat 400 distance in target direction
• flat 3.75 second duration after a .25 second placement time for a total up-time of 4 seconds
• increasing width from 300-500
• blocks All projectiles coming from All directions that pass through it {except bugged projectiles} with no damage transferred to caster
• grants vision in location of placement

now I'm not here to ask for more Nerf to , because i think is an awesome champ, but I'm curious about a few things in comparison.

• why is s starting duration on one of his less defining abilities as a playmaker longer than s main defining ability as a support?
• why does wall size scale, while does not?
• why does CC that hits 's sheild affect him, while CC that hits 's wall get deleted?
• why do abilities coming from behind 's ability get intercepted whilst 's do not?
• why do collision effects such as mundo cleaver/ leona zenith blade effect , while are not triggered on 's
• why does sheild get intercepted by , but not

all i want is answers, not nerfs, not changes, but answers.
