I have found the banchee in halo 4 to be considerably weak, in halo 3 the banchee was feared and players used to cower away from it, as its weapons were more dangerous. Now every player gangs up on the banchee, using lots of long ranged weapons that never used to exist in halo 3. It is terrible to fly as there are lots of vehicles in the maps it is in. it is no match for a mantis or snipers or a spartan laser, and it is on a map with all three, it is annoying to fly as you end up getting shot down in seconds or jacked. I also think the jacking range is too big.
To deal with these problems the banche, needs an armour buff, and more powerful plasma cannons, which could kill enemy players more easily. I hope this gets noticed and there is a buff for it in the future !!!!!!!!!
