I agree completely with Uppity.
I love realism. But I think some unrealstic elements need to be added to KEEP the realism. Running around with a scope to your eye (while possible) should not be allowed period. At some levels, using an m203 in some levels should not be allowed either. In Siberia, with missles lying all over the place, would you use high explosives in an area like that? That's what I thought (I sincerely hope you answered no).
I play with exceedingly realistic loadouts most of the time. My most used loadout is a plain M16A2 with 3 magazines, and two fragmentation grenades (like a real infantrymen... except I would be carrying more ammo; it's for the sake of maneuverability). My second most used loadout is an M16A2/m203 with 3 magazines, 2 m203 grenades and 2 fragmentation grenades. I would like to bring up that I do not ever use the m203 on indoor maps, and I only use them outdoors on outdoor maps (Sicily comes to mind... I will NEVER use the m203 in CQB in the house).
However, I rush. I admit it. Rushing is a very powerful tactic in this game. But it is in reality too. Catching them enemy off guard is an excellent idea. But I don't exploit glitches either. I go prone, but only at far ranges when I am under fire from an unknown source. I also hate using the ACOG (unrealsitically easy to use; the only reason I have one is for dark maps).
Rushing is a realistic tactic. It just isn't realstic currently in INF. I use it to sweep behind defenses in Sicily, flank the enemy in Siberia, and to reach sniping positions in Installation (nothing like getting an iron sight snipe kill). I will rarely attack head on, because not only is it a stupid thing to do in the game (if you can help it), but it is equally dumb in reality if possible to avoid it.
Anyways, unrealistic elements sometimes need to be added to improve the realism. I reckon that if you couldn't aim while running at full speed, you would see alot more teamwork and slower paced gameplay. Although it is possible in RL, it shouldnt be in the game. Besides, how many soldiers have you seen running at full speed with a decked out M16A2 hitting snipers with m203 grenades 20 meters away while looking through an ACOG scope? Not a single one.
