Honestly, I love it, and here's the major reasons why.
1. I like the new buddy revive aspect, as it really helps squads who don't have Medics stay in the fight longer. If you play with a group of friends, and none of you are Medics, you used to be at a disadvantage in previous games. Now however, you can still fight as a squad without needing a medic. Plus, as an airsofter, I love the term "Buddy Revive", and the animation is basically what we do at games with Medic rules.
2. It makes Medics feel valuable. Seems contradictory to my first reason, right? Well, seeing as hoe revives now have an animation, it means that you have to be a bit more strategic about when you revive. And the Buddy revive has a longer animation (about 4-5 seconds if I remember), while Medics have a 1-2 second animation. This means that you can't always Buddy Revive, and it also means that Medics are going to have a bigger role in getting friendlies back up, because they can do it faster. I think that's a great system! Even though everyone can do it, Medics are just better at it. Also, only Medics can revive someone to full health, another good addition.
3. The animations. Gone will the days be of Assault class (BF3 and 4) and Medics (BF1) just spamming revives at everyone, without a care in the world. Now you have to make sure the area is clear, or your team is suppressing the enemy, because now you HAVE to put yourself into some danger. You cant just pick everyone up, and let 80% of the people you revive just die, you have to make the decision of "Will I be safe during this?", giving the game just that much more of strategy.
4. What it looks like when you're downed. Honestly, the first time I was downed, I was taken aback seeing myself on the ground, bleeding out, with the option to yell for a Medic. It gave me just that much more immersion, instead of just being a carcass. I understand a lot of people seem to dislike this, but why? Would you rather just watch a killcam? You can speed up the death if you want, but honestly, its just so cool being om the ground screaming for help. I just dont understand the dislike of it. Plus, if I see a downed enemy screaming for a medic, a small part of me gets some sadistic pleasure from it, especially if I took them down.
But anyways, those are my thoughts. Overall, I love the new revive system, and I want to hear what you guys think.
