CheapestG, man, you demand realism in video games :lol:
Games are pretty much like other talents, you have to practice to get better. Some people are quick with buttons, some people are quick to interactions in the game, some people are just good remembering patterns... Part of the fun is to find your comfort zone. Honestly, I sucked in WFC, very bad! But you know what? The more I play MP or Escalation, I'm doing a lot better, like saving ammo for later, points to spend, smarter plans to revive downed partners etc...
I got my ass kicked so badly when I first started MP (level 0, ahem, ZERO). I almost gave up, I mean I have no chance with those bullies at all! After realizing the upgrades, weapon weaknesses, special abilities, healing spots and most importantly, working together with my teammates, I do a lot better.
Most gamers pick up the pace fast, but I'm always a slow learner :lol:
