Remove stun locking. Now.

"REMOVE PALADIN. NOW" K.

This.

Though I wouldn't be averse to immunities coming into play after the first application in areas like Frontlines or 8v8 when they're introduced. Something like Dark Age had with a 1 minute immunity after a debilitating CC was applied (9 second Slam, 70! second Sleep) and put you out of the game. You had to be very careful in doling a stun or sleep out.

I'm sure such a change will be applied eventually, even when diminishing returns complement the intimacy of 4v4 and not so much chaotic, large scale combat.
