Why Leona is bad, and needs buffs to her E.
First off why Leona is bad- Her E is slow, and hard countered by almost every champion in the game. its predictable, cancelable and its entirely too high risk The high risk aspect used to be justified by her burst damage. Damage she no longer possesses. Current things in the bottom lane that make Leona completely useless.
Janna: Tornado+Eye of the Storm. Pyke: Menchanics in general. Thresh: Flay/Lantern Zyra: Root. Morgana: Dark Binding/Black Shield/Ult. Lux: Root. Taric: Just because he does. Dravens knock aside. Vaynes Condemn/ult tumble Caitlyns traps Zilneans ult Ezreals existence. Lucians damage. Alistar same champ, better in all ways. Lulu Poly/ult. Tahm Kench. Rakhan similar role filling champ, but vastly superior and has heals/more utliltiy. Nami- just bubble yourself when you see the zenith animation. Xerath stun+range Pretty much everything you will encounter in the bottom lane hard counters Leona
The only lanes Leona isn't a bad pick against, and when I say that I mean she just isn't a bad pick...but NEVER is she a good or the best pick. Jihn+Sona/Soraka/Brand Kog'Maw+Sona/Soraka/Brand Ashe+Sona/Soraka/Brand
The only reason Leona has a high play rate is because she is the easiest and most binary support to play, and is the most commonly picked autofill Support as a result. Due to her easy kit(Probably the easiest kit in the game) she has a respectively high win rate at low elos since the microplay is mastered with absolutely no effort, you don't even have to be good at her to maximize her potential. But she is terrible vs even slightly competent players. Just straight up abysmal.
My proposed buffs are simple. Make her immune to CC the moment Zenith Blade tags an enemy champion, if she is CC'd while Zenith Blade is en-route to a target, Zenith Blades connection to a target will break that CC and pull her to her target regardless. a temporary buff "Radiance" Immune all forms of CC for 1.5seconds.
On top of this, her other issue is lack of mechanics and being "all-in" in a overtuned damage meta, where hyper mobility and hyper damage increases every day. 2nd proposed buff, also to her E again- When Zenith Blade connects to a target Leona is granted a barrier that absorbs 20/40/60/80/100 rank1-5 damage, per enemychampion within X radius.
So, rank5 Leona zeniths 1target, she gets a 100barrier. Say she Zeniths into 5 enemies, she gets a 500 barrier. Maybe tune it down at higher ranks, the numbers are off, but the idea I think is a good one for her well being.
is like the best leona counter since he scales so well with armor, provides extra armor for his carry can simply stun the engaging leona and you are overall a ad-all in denier. In ranked an all ad team and leona as a support is my favorite team composition to play against.
