Zed and Lee need their energy regeneration to be lowered.
Energy is supposed to outclass mana in terms of lane sustain. The question is, wether it was done appropriately. Energy management is working for Shen and Kennen. It punishes mindless spam and creates meaninful choices - while also offering their enemies a timeframe to punish bad plays.
On the other hand we have Zed and Lee, both have strong inbuild energy recover on low cooldowns IN ADDITION to the fast regenerating nature of energy itself and high base energy values.
In my eyes Lee and Zed sustain their ressource MUCH to well ad either their base energy, or their free-energy-regain upon skill use have to be brought in line with other champions.
(P.S: I didn't mention Akali simce I believe she has a great and balanced cost for her kit, HOWEVER her interaction with item changes and her passive throw her slightly out of line. E.g. Rylais exra Ap)
could stand to have less base energy regen and more reliance on his passive. Currently the idea of weaving spells and punches is more of an idea than a mechanical necessity when playing him.
is easy to run out of energy. Just stop letting him hit you with Qs. I think
has easier energy management.
