Imagine a character with dual heavy bucklers that were attached to his arms by chains. Think Kratos from God of War except with ultra heavy shields. Makes me drool errytime.

Gigantic two handed shields for bashing and housing a team behind.

Would be awesome if you purchased a certain item it gave you one.

Can you stop spamming? You're making a fool out of yourself, you commented talking shield over 8 times in 1 day.

Exactly why I attached all those bad ass pictures.

A few ideas I have for animations/abilities for a shield champion.

-Dual-Shields used to dash & bash opponents (à la Goofy from Kingdom Hearts)
-Dual-Shields used to crash against each other to make shockwaves (credit to Fly Líce)
-Strong tower shield that reduces dmg taken by you and your allies by X% when they are behind you
-Buckler or triangular shield used as a boomerang (like Crusaders in Ragnarok Online < Must watch this bad ass Ragnarok shield animation)
-Shield used as a barrier by planting it in certain location, all damage is reduced/negated while inside it.
-Shield magic, skillshots are fired from the shield as if it were a cannon (not a cannon shield though, that'd look dumb)
-Shield-surfing gap closer (credit to Mint Häagen Dazs)

And best of all.

-Runic shield that can be imbued with magic/elementals to deal damage:

When fire charged, enemies take damage if you get hit by melee attacks.
When lightning charged, you release chain lightning every 3 hits.
When water charged, you heal X amount every 4 hits.
When earth charged, you receive bonus Armor/MR.
When wind charged, allies gain bonus movement speed when near you.
When light charged, every 3rd attack that hits you stuns/blinds the enemy who dealt it.
When dark charged, you slow enemies around you by X%.
A charge's duration would vary by the element before going on cooldown and could work like Twisted Fate's Pick-a-Card or even better, it would work like the Cannoneer skill Roll-of-Dice from Maplestory, a number would be assigned to each charge and the dice would only roll for 2 seconds to avoid wasted cast-time but chances remain random.

go play WoW.

I think champions that bought a runic bulwark should holds a shield that looks like runic bulwark on their hand.

Of course champions that can't hold a shield, they can put it somewhere else. Like corki and put the shield on the side of his plane, or simply just ignore the champions that can't hold a shield.

Just make a different set of animation for champions after they bought runic bulwark.

The downside is, now everyone will buy Runic Bulwark just for the look.
