Make Akali heal for less of minions
Increase the base heal but then just have it so Akali's passive heals for like 50% off of minions. Doing so would hurt Akali's ability to sustain through lane and force her to play a more aggressive style if she wants to heal for more. This would also allow for Akali to become a bit healthier and would give her more defined weakness and advantages with her passive.
