I literally bought Lulu as one of my first champions (RP obviously) and then played her wherever, and ended up getting Nashors on her and going top (I went with every champ top since my brother mained top then and took me along ><). But then I saw her tag as being support, and got into supporting... and this was when I noticed basically no Lulus other than me and couple other people I saw in bot games trying her out on f2p week or whatever... I never saw her in ranked games (the live spectate thing), nor did I see any Lulus in any of the games my brother played (3v3 old TT + 5v5 SR normal blind pick/draft pick), and I still played her on.
Suddenly, at one point, I started seeing more and more Lulus about, and then whoop. Now I see Lulus in ranked games a LOT.
TL; DR: I played Lulu when I used to see practically no one playing her (last June - August), and I still do, since I'm a Lulu main. I will always love my suppordle~
