>If Luvia would have been part of the war she would have summoned saber class servant. Same as her ancestors and servants true identity would be Väinämöinen.

fukken fund it, but yeah she would suck ass like Rin and her ancestors

The short chronologue of Luvia's appearances in official Type-Moon works:

2004: F/SN is released. Luvia is mentioned by name and gets one line but doesn't even get to even visually appear.
2005: Fate/Hollow Ataraxia comes out. Luvia appears in two scenes. Most people quickly forget about her.
2007: PS2 port of F/SN. Luvia's one single line is voiced.
2008 April: The April fools wrestling joke at the Type-Moon web page shows off a spandex-clad Luvia. At this point she is still so unknown that people think she is a new character invented specifically for the joke.
2008 June: Fate/Unlimited Codes comes out to arcades. Luvia is a playable character for the first time, and she's top tier due to that goddamn OHHOHHOHOHO grab chain that takes off 75% of your life bar. Later in the year F/UC is ported to PS2.
2008, late year: The official-but-not-in-continuity Kaleid Liner joke manga begins. Suddenly HOLY BALLS IT'S LUVIA EVERYWHERE.
2009 June: F/UC is ported to the PSP. Luvia's grab chain is no longer uninterruptible and she is demoted straight to shit tier.
2009: Kaleid Liner's "sequel" KL Zwei starts, Luvia is still the third or fourth most notable character.

Basically, she was pushed from some below-Ilya's-maids tier to an actual fairly visible character in a single year or so.
