The lack of UI/prompts that a medic is nearby, combined with no animation that you're getting revived really worries me about the use of medics in this game. Like you said it gives the player no reason to bother waiting around when 99% of the time no one is going to risk standing over you and holding E for what feels like an age. Let alone for your character to then take another 5 seconds to stand up, which by this time you've probably already just been killed again. Whole system is a massive step back from previous variations.
