You should totally boycott the game until treyarch changes the game and makes it exactly what you want.
What do you want me to do? Accept the lack of weapon variety in the game?
The only thing that's stopping the darn thing from being a decent primary in the game is the fact that it SHOULD be a defensive weapon. I SHOULD be able to use it to defend an objective from adequate retaliation.
The way it stands now, the thing is only a gimmick weapon that has too much auto aim for the protective surface area and too slow of a recovery from a melee.
What if it comes from the back?
Then you die or react normally as if you only had flak jacket.
Everything you listed can be stopped with a well placed EMP grenade, even being stuck with a semtex grenade...
You simply don't have enough time to react and deploy the emp, even with fast hands. Even more so with a crossbow bolt.
The problem is the shield being in the game in the first place. It was pointless in Modern Warfare 2. It was pointless in Modern Warfare 3. It's still pointless now.
I beg to differ. You can hold down capture points quite well if you have a cooperative team.
For example, in turbine B flag, most people will camp at one end of the fallen turbine, you can position yourself so that your just ahead enough to cap the point and not be open to the flank to the sides. And most people will try to kill you before they go for your team so that helps when several people move to capture a point. Slap on concussion and tomahawks with fast hands and you can defend yourself while they throw their Betties at you.
That is, until the hunter killers, semtexes, and rcxd's come out.
