Every stream I've watched has had about 2,000 viewers, and there are indications there are at least that many active players daily for BNS. If it had less then a thousand, NCSoft would have shut it down ages ago. Not justifying the stream rewards, most of them are kinda not great...but keep in mind Hime has ZERO SAY whatsoever what rewards are provided on stream, or any content whatsoever. They're a Community Manager, not a coder...not that it would matter as NCSoft dictates what features and content are added or removed from the game, and NCWest has zero say in any capacity.
This is why suggestions are meaningless as none of them will make it into the game. You can complain all you'd like about it, but at the end of the day, you're complaining to the wrong people and the right people don't speak English.
I will object to your claims that UE4 won't solve lag and performance issues: we've seen countless streams from KR that indicate performance and lag are greatly reduced on hardware made in the last five years or so. It's not perfect but much better then before. Also the game is pretty popular in KR and since we always get updates from KR eventually, it's not really the people in NA and EU working on it (other then translation/voice acting maybe???), but the KR devs simply passing the patches along.
Also I dunno why they won't ban cheaters, honestly. I stopped bothering to report them ages ago because nothing was done. I agree with a lot of your post, just certain facets of it I don't.
