I usually give everyone and everything the benefit of the doubt at first. GWX was no exception. Granted, the weather situation in SHIII is a pain as is the radio messages, but I adapted. Before I loaded GWX and researched all the posts here as much as I could, I read all the quirks and perks of stock SHIII. I came to realize that the stock aspect of the game did well enough, but there was a great deal of room for improvement. And improvements there came to be...
GWX impressed me. It basically redefined "realism" as best it could. Is it boring? No. Are there boring moments within a patrol? Yup....just like in real U-Boat life. If you've seen Das Boot, they had several weeks of "nothing" and their frustration was evident...in the film....they were on 1x TC 24/7....so that can be boring. The GWX aspect pretty much "mirrored" those situations.
So, after I loaded GWX (and Rafael's DSK GUI) and read the manual at least 4 times and perused all the posts I could pertaining GWX problems, conflicts and tips and tricks...I think I "got it". I do not go "overboard" with the TC, my weather changes accordingly. I haven't had 3 weeks of 15kmps winds and rain with 30 foot swells; I periodically do sound checks with the hydrophones. That alone can be useful in a few kills. I no longer expect a merchant or convoy to come to me....you have to hunt for them...just like they did back in the day. So, yes..I can get bored and yes, it gets frustrating, but there is a good payoff in the end if you come back from a patrol with a measly 2100 tons.
Of my personal opinion, sometimes people want "it" and want "it" now and that perhaps realism gets in their way I guess. I am not for the arcade type simulations...if so, I'd be on my DS playing Mario Brothers....
I am learning everyday. Follow most of the rules I can and read the posts here because the info is "priceless".
