There are cool things to do with a shield, but for actual mechanics, here's what I want:
- Position based spell shield that reflects or absorbs skill shots/line nukes (Lux lazer!) to fire them back a second or two later.
- Throwing a buckler that arcs out like Diana's Q, then back again.
- Bash a fool with a shield, then smack them away. Knock up into an optional knockback, basically.
- Some sort of damage link skill, you reduce damage taken for an ally but take some yourself, and vice versa. Could offer some damage reduction as well, particularly for AoE. Would be a nice ultimate.
