Diana assassin?! How do you think Riot can make her a better assassin? If it's a good thing that is

It's no secret Diana is semi-assassin, semi-fighter but she lacks escape tool to perform as an assassin and doesn't have a consistent sustain and defense to perform as a fighter. It's not a bad thing. Her kit is unique and viable (at least in lower elo).

What do you think could make Diana an assassin? Or it would be better if she'll be more an AP bruiser? There are plenty AP assassins with their unique traits. LeBlanc - deception, Kata - AOE and mobility, Akali - stickiness, etc. And even more fighters.

Let's imagine what could be added to her kit so that it would fit thematically and make her better in specific role. Just ideas. No balance. Out of context of current mechanics.

Personally I would like to see her either as an AP assassin or AP diver/bruiser. It would be awesome if she had more thematical interactions with her abilities. -Trails of moonlight. Whenever Diana procs her passive a lighted sigil remains on the ground (only one can exist at a time). Whenever she stands on sigil created by Moonsilver Blade she receives reduced damage. A defensive tool similar to Master Yi W. So that after she dives she wouldn't be blown up by focused fire. -Crescent Strike leaves a lighted trail on the ground for several seconds. Whenever she enters trail left by Crescent Strike she becomes invisible and stays invisible while she on trail. Attacking disables invisibility for a short period of time. Much like Akali W. Just fun idea about Moonlight overall and how it protects Diana. -Allies caught by Moonfall are bestowed with mark. Diana can use Lunar Rush on marked ally. -Lunar Rush resets on kills.
