You are absolutely right, that the European Parliament (EP), does not write legislation alone.

Though the "nothing will happen" is at best pessimistic outlook, at worst obfuscates the relationship dynamics in between the European Parliament and the Commission.

EP's resolution are a strong signal taken by the European Commission in the legislative framework. The stronger the margin of the vote at the EP with more Political Groups, the more likely the item enters legislative drafting/amending queue at the Commission.
