Thanks to vironamas for informing me, and thanks to KayneSlayer for providing the videos:

TWO BAR:

On North American Grand Chase, the two bar releases it’s energy AFTER the skill freeze, rather than during.

RAGE MODE:

On North American Grand Chase, the Rage mode lasts for 20 seconds instead of 5 seconds.

Thanks,

Brought up by Vpower, Ntreev has “nerfed” (or fixed) Jin’s second job “repeat kick otto”.

Anyway, you can see the whole specifics in this video provided by Vpower.

Thanks Vpower:

Well it was confirmed in one of Loki’s posts that Amy will no longer be able to stay in the air for more than 4 repetitions.

We are aware of some other outstanding glitches along similar lines and we have relayed that to KOG as well, but there is really no way of estimating when a fix for a given mechanic will be ready. Once it is, we’ll roll it out after testing.

In an effort to maintain the unique mobility of the Amy character, the combo was not removed entirely but rather limited to a specified number of executions before falling. This is in line with the fix previously deployed for melee infinite combos and we feel that it is an appropriate compromise.”

This simply means that you aren’t allowed to infinitely fly on NAGC anymore
