There have been no realism packs. They're all competitive. BKT (Blockombat) has some realistic features, but it lacks the animations and realistic fire rates, effects etc. You cannot tell me H&K is realistically designed. TS weapons were MADE for competitive servers. Warfare was like BKT, it had some realistic features, but not all the ones that would actually make a convincing pack.
Realism, especially combat-wise has not been milked dry, nor has it been milked. The gutters have only been TOUCHED by a couple people, who have then decided not to take the risk due to the exact argument you're putting up with me. Let some people give this a shot.
Im not giving up.
Ftfy.
OT: There's another side of "realistic" as well that comes into play, and that is practicality and aesthetic. Another reason why introduction of realism will not work in Blockland is because 1) realistic models will not be aesthetically pleasing. If you try to pursue realism in the weapons, you would do well to try to imitate realism with builds, playertypes, vehicles, and other content, and at that point, the game is pretty much no longer Blockland, and because Blockland has engine setbacks and inadequate physics for "realism", you should probably choose a different game to play where realism fits better. In addition, such a change within Blockland would be much more work that it's worth. 2) If you want practicality on top of realism, your best option would likely be to find the closest pack to realism that fits aesthetically to the Blockland style, such as the BF3 pack, and just edit it so that it is realistic.
The thing is, you're setting up unrealistic expectations for Blockland. This has been discussed over and over because of these reasons. I am not going to say any more on the matter, and I will not make any attempts to hinder production of this pack. I wish you well in your production of this pack, as I cannot deny, there is a demand for this kind of content within Blockland.
Good luck.
