Divine Shield doesn't grant invincibility time

Describe the problem. Be as specific as possible!:

Before yesterday, Divine Shield (4th job Paladin skill) had a "GUARD" feature, where it would prevent you taking damage. This used to go with the typical ~2 second invincibility from attacks. It blocks 6 attacks, so it would last 12 seconds or more.

Since the Aftershock patch, it blocks the damage, but you are never invincible - magic attacks, other attacks from the same or different monster, anything can hit you instantly. As a result, there is no minimum time - if you're unlucky, you get hit 6 times the instant DS starts and it lasts no time at all.

As such, Divine Shield is pretty much useless - it lasts practically no time against mobs or anything that casts magic attacks.

More of a problem - there's no "invincibility time", so status effects can be cast on you even if you just tanked touch damage. This means that, for example, Zakum can stun, seal, no matter where you are in the room, if DS is active. Any boss that chain-stuns (eg. BGA) is near impossible for a Paladin to attack, because they have no way to avoid the stuns.

Two Reindeer attack me. Each of their attacks consumes 3 "GUARD"s, and Divine Shield is instantly cancelled. (all 6 are directly above the player so you can't see 3, but the buff icon's gone)
