I think we can agree on that shot lag problem caused by waiting for database (which I've already fixed) was really bug (it was absolutely random etc)
The second problem is systematic and changing it would have medium impact on gameplay which means it definitely IS custom change. I'm starting to be against it as it seems this feature was present on gracia final, epilogue and probably freya as well. So if someone really thinks it's bug and NCsoft solved it in some version, give me some proof - link to offic forum or anything else valuable
