Am I the only one who believes that Lee and Syndra don't need buffs?

Title. These characters have historically been rather strong, and in Lees case I cannot remember a single time throughout his existence where he hasn't been dominant or popular. Remember season 4 Syndra where she was stunning 3-4 people, and one-shotting carries? Because I do. I also remember that her fall in popularity coincided with the mana-regeneration changes. Of all things, doesn't need additional damage, but rather a touch-up on her mana-costs to stand-up to energy/cooldown abusers like Yasuo and Zed. Lee, on the other hand, certainly did not need more options in his kit - and rewarding using his ultimate on high-hp targets should come at the cost of making it weaker against squishy targets. All it does now is eliminate the prospect of making a poor decision as Lee - no character should ever be rewarded for initiating on a tank if they can also completely blow-up an ADC. Simply put... what gives? I've read the patch notes, watched the rundown, and the logic behind it makes no sense especially considering that they didn't take anything away from him in order to give him that power. Is someone at Riot willing to walk us through their thought process because "rewarding bad players" is the worst possible design logic I've ever heard across the entire gaming genre.
