Suggestion
May I suggest that what this template currently utilises is replaced with the following:
{{#if:{{NAMESPACE}}||[[Category:All articles with unsourced statements]]{{#if:Category:Articles with unsourced statements|[[Category:Articles with unsourced statements {{#if:{{{date|}}}|{{#if:|from|since}} {{{date|}}}}}]]{{#if:{{{date|}}}|{{#ifexist:Category:Articles with unsourced statements {{#if:|from|since}} {{{date|}}}||[[Category:Articles with invalid date parameter in template]]}}}}}}}}{{#if:citation needed|<sup class="noprint Template-Fact" title="This claim needs references to reliable sources{{#if:{{{date|}}}| {{#if:|from|since}} {{{date|}}}}}" style="white-space:nowrap;">[<i>{{#if:|{{{pre-text}}} }}[[Bulbapedia:Citation needed|citation needed]]{{#if:| {{{post-text}}}}}</i>]</sup>|}} - unsigned comment from Tmwps (talk • contribs)
