Veteran's Scars needs a buff.
Right now, Runic Armor outclasses Veteran Scars at nearly all points of the game. Even those without any built-in healing or shield in their kits take Runic Armor instead of Veteran Scars because of the commonness of shields and healing from teammates plus potions and HP regen.
50 HP is simply too small. Veteran Scars needs to have some sort of scaling HP to make it a more viable choice. I mean, wasn't it reworked to make it more viable for ADCs? Very few ADCs even take it because Runic Armor is undoubtedly better.
Buff Veteran Scars. Make it give something like 50 + 5% max HP. That should at least make it more compelling to take.
sorta thing where taking damage gives you a grey health that regens but just very very small
combo even more. Would you rather have 60 more HP as a 3000 HP tank, or extra regen to get it all back faster?

life steal or
hp steal on monsters... and the healing from using smite on large monsters
