Sorry on to finish my thought had to run to pick up friend and just spazzed on the reply button.

The thing we should consider is that in pnp per creater of 5e on his healing fountain spell (unsure what it's called atm) is that yes they know it's broken, yet in 5e they were looking at the party being fully healed when the encounter began. Another thing to look at is in my above post the ability for the DM to quickly stock a few healing potions in the campaign versus the video game where there is no gm to figure out if that fight went to shit to for the party, making them use up alot of their resources, more then what the encounter called for.

Then there is the pacing difference between pnp, and video games. With pnp you can call breaks as a DM refigure out the encounter, have the party chat as you do so, while your working behind the scene to figure out why a fight went wrong, then adjust the next one, and let the party heal up through short rests, or long rests. Again you can't do this in a video game, some people don't realize the need for these rests and taking them more often then they think they do. Though it can be abused in it's current form, well the long rests, short rests you get one per long rest. Also note the ones who wrote 5e expected you to be fully healed in an interview for each encounter.

Then there is pacing determined by the DM in pnp, in video games alot of times your simply walking from one fight then another, burning your resources as you go, resources that have a finite amount per what ever rng list Larian is using. Again in pnp the DM can add anything they want at any time, video games it's the luck of the draw. Will adding a cantrip for clerics to heal the party back to the full health that is expected by WoTC to be true before each encounter be OP. According to the author of 5e it is, but it's the way 5e was designed.

Aid being OP, using of a spell, or skill check. - You bring someone back from unconsciousness to a grand total of 1 hp at the cost of your action, and possible most of your movement. Next turn creature farts in the direction of the recently aided character he falls again. again another aid is used for the cost of a full round action, bringing fallen into a fart away from death again. How is that OP?? The fact that your using your action which means you are doing no damage, while your enemies are all doing damage. Then to top it off that character has to stand up, wasting much of it's movements to do so, probably will need to quaff one or even 2 health potions to survive another fart in his general direction. A thing that may or may not happen do to initiative order, or if he's standing in a puddle of acid, or what ever. Which with the way things are working the AI is going to target him on their next round, forcing again the loss of not one turn of damage but 2. The fallen character and the one who is doing the aid. Damage which may very well turn the fight in your favor, forcing you the player to decide if they need that damage, or can risk having to use a revive scroll to get them up after battle if they die.

Spells have a finite amount except for cantrips between rests. Again it's action economy, forcing you to make a choice, the less actions your using to damage an opponent, or hinder their ability to do damage the more possible damage being done to you by the very nature of the fact the battle is being prolonged. The longer a fight is prolonged the more likely you are of running out of spells you may find yourself needing, or health potions, revives etc. Forcing you yet again to take a long rest, or short one depending.
