Changes to Thunderhead Meta?

Patch Notes Jan 22:

"Changed reward chests for the "Defeat the Wrathbringer" and "Defeat Sulypix before it drains your reclaimed oil" events to be awarded once per character per day instead of once per account per day."

I ran these on a couple different characters and only got the Light of Deldrimor key once, the rest of the time I got a wiggle chest with a few pieces of trash loot. Does this change not effect the key limit because the only reason to run the Meta is to earn keys to use or sell.

“Moved the Light of Deldrimor Plate halves out of the boss chests and into event bonus chests, which are available once per account per day.”Next time keep reading, the answer was in the next line of text.
