what if we turned boneplating into its own keystone?

since its introduction, it always felt kindof mandatory as a rune to pick up for the lane phase (if youre going into resolve). half of the reason is probably because its the only defensive rune in that row, and enables people to simply pick up 3 runes that help them deal with enemy champions, instead of two.

but i wonder if riot ever considered introducing a directional shield to the game.

imagine it similar to fioras vitals. you have 4 shields in the cardinal directions around your character model. if your champion gets auto attacked or otherwise damaged from a certain direction, it consumes the shield and absorbs part of the damage.

the 4 shields have a respawn timer out of combat. lets say 30 to 10 seconds based on level.

would this be something people could be interested in?

edit.:

• boneplating becomes its own keystone
• revitalize replaces its spot in r1
• demolish now grants a permanent defensive buff for taking down turrets (lets say like 20 health per turret)
• legendary guardian is readded to the game in r2
