To add to this.
Halo games normally come like this....
Around a three year gap between core Halo games that mark a significant important/difference/milestone in the franchise.
Halo Ce 2001 Halo 2 2004 Halo 3 2007 Halo reach 2010 Halo 4 2012 ( 2 year timeframe ) Halo 5 2015.
Just because you don't like the direction the game is going does not mean it is copying Cod and they are going to release Halo every year.
Besides what ideas are they "stealing from Cod?" none, Cod does not own the right to use the killcam, nor does it own the rights to sprint.
Halo 5 is more like Halo 3 than Halo 4 trust me to that.
For example everyone has fairstarts. Everyone starts off with the same weapons.
Besides its a BETA! You cannot expect everything to be perfect, you are testing the game, problems are to be expected.
