-snip-It is not impossible in any way. You can just shoot a bit and then melee and your enemy is dead. Get near your opponent, combine your SMG with a Plasma Rifle or a Magnum and that's it.
Also, you described a situation before were the enemies had all of the power weapons. If they have them, they cannot have all of the BR's and Carbines too, so you can use them to fight back. And as soon as you kill one of them, that situation dissappear. If you think dual SMGs or any other combination is worse than a BR in close to mid range, I don't think you're using them properly.
I agree that the BR lets you assist a teammate from anywhere, but that breaks map design and it turns into a single weapon game with no range limit. I have my opinion, you have yours. Many people think like me and like you, even if we're the minority there's no reason to completely ignore us. If that's the case, make it 30% SMG starts and 70% BR starts and then both sides of the community will be satisfied.
Also, for long range maps it's ok to remove Smg starts, but to have Br starts in the close ones is non sense. You can't even find a suitable cover that doesn't get exploited from an angle. Think of Midship.
Maybe not 100% impossible but it is highly unlikely that you will retake map, power weapon, or power up control with SMG starts once the other team has the aforementioned. And it is a little laughable saying that all you have to do is get close to an opponent, shoot and melee. That might works against bots and the absolute lowest level of players, but against decent or seasoned H2 people, you will not get close enough to spray n pray. That's the essence of having map control, the team without it doesn't gain position for free anymore. The scenarios you're describing, don't actually exist in classic Halo.
And yes 4 players on the opposing team can have all the BRs, Carbines, and power weapons on most H2 maps with SMG starts. Each player can hold 2 weapons, and since most maps only have one or two Battle Rifles at most, that leaves 6 open slots for the sniper, rockets, sword, sniper, plasma pistol, carbine, etc. One of the unique mechanics in Halo 2 is that a power weapon will not spawn again if a player is alive and holding the gun, even if the ammo count is empty.
Also L0rch is correct, any combination of dual wielding in H2 will lose to 4 BR shots at mid range every single time. The time to kill is too fast, although your aim has to be on point and the last shot has to be a headshot. The only time dual wielding wins the engagement is if it is super close quarters; but then I'll probably just BXR or BXB you instead.
"BR lets you assist a teammate from anywhere, but that breaks map design and it turns into a single weapon game with no range limit."
Alright let's dissect this one and explain why it is completely false. In H2 you actually cannot assist your teammate from anywhere on the map, obviously not on the larger ones, but even on the smaller competitive maps there are walls, barriers, obstacles, and geometry that all affect lines of sight. A good player with proper positioning skills and movement will get many assists, but to speak as if a person with a BR can run around a map in the open just shooting everyone, just isn't how real mid to high level matches of Halo 2 play out because you will be punished and die quickly. I feel like your statement ignores just how useful the Sniper, Rockets, Sword, Shotgun, and Plasma Pistol all are in H2. Also the BR has a severe range limit, not as bad as the H3 BR but certainty much shorter than the CE pistol, so that is incorrect. In you think you die very often to a BR from far away, well....stop standing still and start fighting back.
And saying that it breaks map design is just a poorly researched opinion. If that were the case, why would thousands of people have traveled to compete in tournaments with BR start settings? Why would tens of thousands of people watch them play MLG variants on live stream and TV? Why would we still play the game the same way competitively today? It is because utility weapon starts make the game, not break it.
"Br starts in the close ones is non sense. You can't even find a suitable cover that doesn't get exploited from an angle. Think of Midship."
Again this statement is purely ignorant and painfully oblivious to how the game plays in the real world. BR starts work beautifully on small and medium sized maps. There are tons of places to duck and find cover, and getting the right angel involves risk to move to a different position or be out in the open. It's pretty clear you have the most bottom of the barrel knowledge and experience in Halo 2 so please, please try to educate yourself
and play more serious matches or watch higher level gameplay to gain an understanding of how the game works. It's hard to take your posts with any sense of credibility when you spout nonsense for a low effort discussion.
