Not true at all. When we used the MP5 it was full auto, even the new M4 Carbines and rifles have burst fire on them. Yes, even the SOPMOD. The Para-saw is full auto, not to mention all the specialty guns I won't go into here. Not sure where you dug up that information but it is wrong. Absolutely wrong.
With Melta guns right? That was a huge problem in Space Marine. People taking advantage of the thirdperson perspective to remain unseen yet allowing them to lie in wait and ambush peeps killing them almost instantly.
Well, that's because in Planetside 2 you need ~5-10 hits to kill someone (depending on weapon, range, and whether they have nanoweave) and their typical engagement range is about 30m. In that situation, the time you spend pulling the trigger 5-10 times costs far more than the time for your gun to cycle through a few missed rounds on full auto. They also have this weird thing with burst fire where the first two shots will be right on top of each other, but the third will go wide. This means that 3-burst weapons are basically 2-burst weapons that just waste the 3rd shot most of the time, while 2-burst is basically a semi-auto that does double damage. I'm not sure why burst weapons in PS2 do that, but it's a fairly consistent behavior and it does not occur (as far as I've noticed) when firing short bursts on full-auto mode. It's also what makes the Gauss Burst awesome. However, even in PS2 switching to semi-auto can actually give you an advantage in those rare firefights that occur at 100m+. Particularly if you have a high-ish damage weapon with a good muzzle velocity, like the Gauss AR.
I was a SAW gunner myself, so woohoo for full auto! It's also a whole lot easier to keep a SAW on target in real life than it ever has been in any game.... That being said bolters arn't full auto, or even burst, they are semi-auto with a fairly slow cycle. There was an interview with the artists at GW one time and when asked about that, and about lasguns ejecting shells, the answer was to the effect of that visually there was more impact with shells flying out at a high rate of speed. From a gaming perspective, I would prefer slower firing with more impactful shots, even if the overall DPS between the two modes stayed the same. It would mean that your aiming with individual shots is more important, and it would also allow for carrying realistic amounts of ammo (IE: 90 rounds instead of 300). All that being said, the RoF as seen in the alpha was said to be at least twice the currently planned RoF.
I'm excited about it. It will be interesting too see how the rest of the mechanics evolve after what we've seen in the video. The texture and models all look amazing, especially as a alpha.
The M4A2 has burst.. that's "Big Army". You wont find many A2's in Ranger Batt. or the higher tier units.. they're all A1's. When you shoot every day and learn to really place rounds... you don't need burst fire.. you make it happen (only tighter and better) with full auto or semi. I don't know any real operators that have anything good to say about being hindered mechanically. SUA SPONTE!!! and Aggressors Beware!!!
Eh, the M16A2 has a 800 rounds per minute cyclic fire in semi-auto, but most of the armorers aren't talked to/cajoled/bribed to modify the trigger to make this possible, but I did it for a few people. Semi-auto doesn't equate to "slow", so much as "fast as you can pull the trigger".
