Some PTB thoughts generally
I am not sure there was a discussion about that, but here is some thoughts from me about PTB. Not that one, but all together.
First of all, it should have a good, strong backbone. Not too many people go to the PTB (comparing to the alltogether playerbase). That last one was horrible with that latency issue. I know that the devs worked hard to find the problem - but it should extends the testing period. Maybe it would delay the release date, but that still better then not gethering enough relevant information, and change the game after those experiences.
The games should work like a custom game (without the map choose option). The point of it to TEST out things. Now you have to spend points in the bloodweb. Maybe you get what you want, maybe dont. Maybe you had enough BP when your account got mirrored there, maybe you don't. And this is even a bigger problem when new characters comes out. When it is only about a change, you can use those things, what you already have. But how can you test out some items/perks/addons when you not even able to get at all, or too few for a test?
And I think the devs need those tests, since the players many many times find something, what the devs had no clue, or they just think about it on paper.
