Regarding criticisms people have of the Healing in the show - what is annying me is they are completely ignoring the physical cost. Until late in the Third Age all Aes Sedai Healing took its power from the recipient (with the exception of the Healing weave used to refresh strength which took its strength from the caster).
It wasn't until late in the Third Age when Nynaeve al Meara rediscovered an ancient Healing technique which draws its power from the Source - I *think* she was inspired with the Aligning the Matrix weave from Damer Flynn to then use all Five Elements in different way, as opposed to the usual Healing which focused on Air, Spirit and Water.
The show has completely ignored this - not even an acknowledgment like with Matt just eating constantly in the Tower. Aes Sedai can be near death then healed and start throwing around weaves, this is not how Healing works.
This isn't just "healing magic" - the Wheel of Time has specific sets of metaphysical laws, things work in a particular way and if you just start tweaking here and altering there you end up with something that isn't even logically consistent. The same can be said with Season 1 when the whole Dragon Reborn search also included the women - despite the Prophecies being very specific and clear the Dragon Reborn must be a man.
It's these sort of inconsistencies that just don't make sense to anyone familiar with the books. Healing all ailments without any consequence is not true to the source material.
