I quite honestly don't believe the E3 demo did any justice, it only looks like BC2 because they chose a small closequarters map for showcasing, and there's probably a max of 24 people playing it (i am of course talking about the streams that showed people playing it).
It just looks like Battle of Brest(16) played with 32p.
I'm not sure where they got the idea for tank regen, but the health regen system they had in BC2 worked well enough for medics to feel like they're actually doing something,
said regen is actually quite slow and the medipacks accelerate the rate, nothing more.As for the spawn points, I think only the SL will be spawnable, after all, SLs will all have little stars, and by their own words "cut off the head and the rest falls apart".
I'm not entirely sure about the animated knifing, I think it is better than the
COOOOMMAAANDOOO I sometimes have with BC2 and CoD, maybe if I had a PS3 and Killzone 3 I could at least make a comparison or the such, replacing the knife entirely with an animation makes it feel like it has more use in a panicked or stealthy environment.
I like the BF2142 class layouts, at least you can't complain about medics using LMGs anymore, I don't see anything wrong with squad members (more squad leaders, more spawns, more action, the better right? Right?), and the absence of the commander is, at least to me, not good nor bad, it WAS a Battlefield 2 element, but look at the rules behind that element placed by the community, commander can be fun, but at the end of the day I would want to be where the action is and not staring at a map for the entire round.
in the end, as cannonfodder said, can't really judge a book by its cover, we'll do that on the September Open Beta.
