My issues with Halo 4 are when strategy and teamwork are no longer being rewarded. Ordnance is an issue for strategy because of the concept of risk vs reward. Basically, when weapons spawn on map, it is always a risk to go get them, especially better ones like rockets that are usually in a dangerous position. You have to risk moving to a new place and going into a bad position to get the reward of a weapon that can allow you to get more kills more easily. Personal ordnance rewards you for getting kills with the ability to get more kills. You no longer have to risk anything to get power weapons, and so you are rewarded for winning a few fights with a weapon that will increase the likelihood of winning the next fight. This is bad for good and mediocre players. Good players will likely get more weapons than they would have normally, making them win without having to risk anything. Average or lesser players will eventually get a free power weapon and then get a kill or two with it before being driven into the ground.
Neither system really helps out the less skilled player, but the new system frustrates the strong player because using these weapons this way feels cheap, and there is no way to deny the other team getting power weapons.
Also, the reason I'd prefer secondaries not to be the way they are now also stems from the fact that BTB maps used to have plasma pistols on them to find, fight over, and use against vehicles. This system allowed some to be in the map but limited them, just like camo being on the map did in previous halo games. I love the plasma pistol when used this way, as it promotes player movement and it helps balance out the vehicles, but when everyone can have on and death does not make them lose it the strategy disappears and the game devolves into a team all spawning with one until the other team has lost their vehicles. I miss designing BTB maps around plasma pistol locations, it really was a great system in Reach.
Ways to kill a vehicle in Halo: Reach:
• Team shoot it until it is dead or very damaged.
• Find a power weapon on the map, or a plasma pistol or plasma grenades to damage or halt it.
• Be a sneaky ninja and hijack or board it.
Ways to kill a vehicle in Halo 4:
• Plamsa pistol it and either board it or stick it to death with your team.
• Team shoot it if it's a banshee.
• Drop in your team's often unused personal ordnance and kill it with a sudden onslaught of power weapons that the other team had no control over.
