Whenever I get suppressed I go find cover and two seconds later I am fine again. I dunno, I don't think it's that bad. Just put your sunglasses on and deal with it.
No, but seriously... according to an interview with DICE they are going to lower the suppression again in the next update. I forgot who they interviewed, I think the producer, and I don't have the exact quote but basically he said that "we knew where the min was before, now we know where the max is, so we are going to find a middle ground between the two".
I think people often forget the complexity of balancing a game like Battlefield. I mean here is a game that you can play online with 64 players. Every bullet travels in real time, there are different classes....each with their own specialization, there are many different vehicles, even armored vehicles,...tanks, helicopters, freaking JETS and rocket launchers and somehow all of them have to be balanced while still retaining their own individual trademark feel that makes you say "yes, this is how an M4 should behave". On top of all that there are large open maps, tight close quarter maps, but the game needs to feel evenly balanced no matter which map you play. And it needs to appeal to all sorts of different play styles.
I dare any company to try and get this perfectly right on the first try.
