I've also never, ever seen a BF3-style medic train in a BF1 round. The only time I've seen mass revives is when a bomber or attack plane or dreadnought blasts a friendly controlled flag and medics can pick-up a whole gaggled of people in effectively perfect safety.
+1... Given the fact that the math in conquest has changed to give more weight to objectives, less points for revives, less opportunities to revive in safety, more dead players opting out, and given that a surprising number of medic don't even equip the Bullshark Testosterone needle or don't revive me when I'm 5m away in total safety, I daresay revives are in a mostly good place because the reward is less and the risk is greater... If the Medic was that much of a gamebreaker I'd see a lot more people running it -- But on most maps it seems a distant third to the Assault (LOL Hellreigel) and Support
And for all the bitching and moaning about suppression in BF3, unlimited revives at 100% were by far the most broken mechanic because no matter the situation or danger most medics saw a free instant 200 points and it also encouraged really stupidly aggressive suicidal gameplay with no detriment to their KDR whatsoever (This was compounded even worse by the Assault class having far and away the best weapons in its arsenal)... We all know that dude from BF3 Metro max tickets who would go like 65-20 even though his name was always in the deathfeed and you probably killed him 20 times by yourself...
If we're gonna tweak something, for the love of God make it the vehicle spawn system...
