Kalguuran Seafarer Supporter Pack Shield MTX

Hello, i recently purchased an upgrade to my Kalguuran Seafarer Supporter Pack, as I was particularly interested in the Shield MTX effect included with it.
However, I have noticed that the scale of the shield appears disproportionately large on most character classes, significantly larger than any other shield available in the game.
Could you please clarify whether this is intentional, or if it is an issue that may be adjusted or corrected in a future update?
