As I displayed above there is a bunch more healing and sustain. Some big differences are **Vampirism vs. Ravenous Hunter** which I think is one of the biggest problems with healing because it offers a bunch of healing on champions that were never designed to have healing. **Dangerous Game vs. Triumph** which more than doubled the healing. **Secret Stash vs. Biscuit Delivery** which straight up gives you 4 biscuits that grant 15% missing health and mana back which is insane to the 30 hp buff your old pots got. Aslo it forced you to buy potions meaning you had to spend gold and time to back for them.
I just don't see how this has not been identified as a major issue. Since healing is so high and everyone can get it damage has to be higher so that people can't just out sustain the damage with all the healing that is availble, plus poking people out is so much more difficult, so people are less punished for playing lane poorly. League of Legends really needs to have this looked into if we want the game to get fixed. Just remember identifying the problem/problems is the first stage of recovery.
