which is the best leona ship

Probably a littoral combat ship, also known as an LCS.

I absolutely love the Diana/Leona relationship and would pay to hear more of it. I don't think it needs to be a romantic relationship (though the fangirl I hide below my manly facade would love it), but I like to believe that they have enough in common that they could sympathize with each other, or that at least one of them has a history of feelings toward the other, as Diana might have admired Leona before being faced with execution. It's fine to me to see them act antagonistically toward each other, so long as there is at least the thought that, given a chance at a real conversation, both of them would find they had a reason not to kill the other, perhaps even to work together or build a difficult friendship.

As for Pantheon, I'm all for him being good friends with Leona and having a strong, deep-rooted relationship between them, but I'd be a little aggravated if it turned into a romance, as it would make a strong (possibly romantic) relationship with Diana more difficult and unlikely. Honestly, Pantheon is not an interesting enough character for me to care about him for any reason other than that he is loosely tied to Leona. There are some fan creations that make him more interesting, but he is canonically rather boring.

Leona x diana is cute af.

Well, I first shiped Leona x Panth because that one made more sense, but I still liked Leona x Diana because the artwork done for them is really adorable (look up Dianamoonfall on Tumblr, or the Kalista/Leona/Diana comic). However, after I looked up some of the background lore on Leona and Diana, I saw a post by Ironstylus on a thread about Diana's lore: "We want them to be intertwined, and without delving too far into assumptions and implications, without getting too detailed about their past relationship, what is more tragic than to have to kill someone that you love?" (http://leagueoflegends.wikia.com/wiki/Leona/SkinsTrivia), I'm kinda leaning more towards that ship. I really only pair couples if the lore supports it, with a few exceptions (Sona x Draven, thanks Zulidoodles)

why choose regular shipping when you can have LESBIAN shipping?

I remember a game in which I played Leona support to a Draven, with a mid Diana. In one 3v3 fight, the Diana player initiated with a Lunar Rush/Moonfall, on top of which I dropped a Solar Flare followed by a Zenith Blade/Shield of Daybreak, and Draven walked away with an easy triple kill. The point is they compliment each other better than Leona/Panth, who have no real synergy, on or off the rift. Panth is a loner, I think
