That was a lot of text to type to say nothing of relevance, and still be wrong. The Gjallarhorn is a quest reward. The pre-order one has a different skin to the standard order one - that's the only difference. One still has to buy the content either way. Pay2win has zero relevance on something that will be available through playing the content. Do the quest, receive a Gjallarhorn. Don't do the quest, don't receive a Gjallarhorn. Preorder the content, receive the black/silver Gjallarhorn. Don't preorder the content, receive a white/gold Gjallarhorn. The weapon is not exclusive to pre-order players, ergo your Pay2win references are rendered moot.
