umm.. In BWL u have to kill 1st boss to go further. Actually gates wont let u pass. If u try finding in model editing exact gates, and change them on smth that can be bypassed, maybe u can get through them.
I found out that such things as gates are clien side. Because when i went to deadwind pass with friend and try that exploration area at GY we had interesting situation. We everything did as in guide on getting there said. We went there, looked at the place and on the way back, my friend didnt see gates anymore. while i did. I couldnt bypass gates, but he could. I saw him running through gates. I think he had some error on loading model so he bypassed it.
