If you were to think about the hundreds of hours that went into the building the supermods, the fact that people did it for free and gave it to you for free, to come in and say "it sucks" is quite rude, you think?
You do have the choice of not using the mod. Or, you could go PURCHASE an expansion pack. I hear there's one available and may even contain some of the features you see here. <additional comment self censored>
The stock game is quite arcade. It's easy mode already. The modders went to a lot of trouble, time and effort to do research on how things worked historically. I think all of the supermods did an outstanding job of adding to the immersion, adding tweaks and tools to make the experience more enjoyable, adding realism including expectations of weapons performance. And they had to do this within the confines of the SHIII engine.
I for one am quite appreciative of everything they, as well as other modders and tool authors, have done to add to the game and the community. I wouldn't dare to say anything "sucks". If it's not my cup of tea, I just don't use it.
My teenage daughter is watching me reply to this, she asked me add this "It's called skill baby, get some". (She plays NYGM on full realism.) She also suggested that "Quake and Counterstrike have weapons you may like."
