You posted in your post that they were same in effect, but not use. Now you're saying they are virtually the same? The role and function of the weapons and mechanics you listed differ extremely from game to game. Halo has equal starts that spawn you in only with starter weapons, and force you to fight over the power weapons that spawn on the map. Destiny spawns you in with all the weapons you can use, as well as a slowly recharging one shot/revive/shielding ability. Weapons in Destiny call all be aim down scoped, making them considerably more powerful at longer range. Even in Halo 5, ADS only provides a slightly longer range and, with auto rifles, a slightly reduced bullet spread. That's just some of the differences. I've already written a wall of text and don't want to make a Great Wall of china.
