YMMV / Teamfight Tactics

• Badass Decay: Leona was changed between Seasons 1 and 2 from a Tier 4 unit which used her classic ult as a devastating AoE CC which would turn the entire battle into a piddly Tier 1 unit that only uses her defensive buff to make her briefly harder to kill. It doesn't even explode to do damage like it does on Summoner's Rift. The only reason to use her is for her Lunar synergy with Karma (there are only 2 Lunar units so you have no choice about using Leona), which is extremely powerful.^note Her other synergy, Warden, is almost meaningless, as Warden is the most over-represented class in the game, with 9 units to choose from for a synergy that only goes up to 6 anyway.
