You need a weapon?....You can find your own......
In reference to the hunters....I actually liked how they were easy to kill, as long as you had the correct weapon. A lot of the enemies in Combat Evolved were like that. For example, Jackals were bastards and would only truly succumb to a charged plasma pistol shot, grunts+pistol=-blam!-, in order to take down elites efficiently you had to use a mixture of plasma pistol/rifle and pistol/assault rifle. Also, hunters also usually came in with other infantry, making it so that you have to do deal with the others so that you can focus on dodging and one-shotting the hunters. Hunters in Halo: CE also made up for their weakness with those insane plasma cannon lofts that would destroy your scorpion in 2 shots! In my opinion, I liked it more when each covenant had a strategy to them. While the hunters were weaker, they were still capable of being complete bastards if not taken seriously.
