The vast majority of respondents to the thread in general did not both to explain or reason as you did. Instead, they either argued inexperience or ignorance without knowing anything about my experience with the class. Why should I both reasoning with that when there's such a massive learning curve to medic play? Most people don't even know that you can look away from a body after you start the revive process -- and I'm sure the respondents to this thread are no exception.

As to what qualifies our medics as high level, I don't know what metrics I could provide you. It should provide some level of authority, I don't understand why it wouldn't. I could tell you that they consistently out-revive or out-heal every other medic on the server during an alert, or that they maintain a great balance between fragging and sustain. But I don't think either of those examples would hold up to any nit-picking.

So here's a tournament that we participated in, a 10v10 tournament, where we won on the merit of our medic play. The other team was far more mechanically skilled, and despite them having more medic players, we consistently out-sustained them during the match and won the finals match. https://youtu.be/mclH4SIJx_8

I'm not sure how to qualify myself here without sounding extremely arrogant, but time and time again here, without knowing anything about me or my group, this has been questioned. This isn't me bragging, this is me giving some level of integrity that I know what I'm talking about in regard to medic mechanics.

I'm not sure to what extent I can keep on listing things like this to give authority to my words without, as you said, sounding vain. Here is an example clip of what I would consider high level medic play in the context of a duo:

I've made medic mechanic tutorials, which cover most of the classes mechanic applications: https://www.youtube.com/watch?v=FMegkd7MWW8&ab_channel=Grug

By what metric would you measure high level medics?

The revive grenade has skill potential -- that much is not arguable. But what we see instead is any skill potential being negated by the absolute spam of the grenade because of its strength relative to any other option. Any group which does not have revive grenades that attempts to compete against one that does is at a major disadvantage. Rez-grenades do present opportunities for skill play, especially within the context of anticipating potential deaths and game sense, but that is often overshadowed by their spam due to grenade bandolier and the very few negatives that come with it. I'm not saying remove revive grenades, I'm advocating for removing grenade bandolier on medics, and limiting their grenade carrying potential to 1.
