A closer look at these Leona "buffs"
Passive - Sunlight MARK DURATION 3.5 seconds ⇒ 1.5 seconds DAMAGE 20-105 (at levels 1-18) ⇒ 25-144 (at levels 1-18)
The extra damage is nice, and its definitly going to help leona throughout all stages of the game. But then we look at the mark duration. in solo queue, no ADC will be able to proc that mark in 1.5 s I guarantee it. You have to be really co-ordinated with your adc in lane to proc marks, so Leona has basically been made the ADC's bitch. Slow adc = rip leona's passive proc.
Q - Shield of Daybreak COOLDOWN 9/8/7/6/5 seconds ⇒ 6 seconds
THIS.
First riot's balancing team GUTS the base damage on leona W. and makes it so that you have to max Q in lane. NOW, they ruin Q max too.
What do you want from leona players riot? Do you want them to quit leona?
