You mean something like importance of thinblood discipline choice bcs traversal uses?The video game community is a very fickle bunch, & quickly turn on devs who promise something-however small-then fail to deliver.
On the other hand, there is allways the way, and we seen it few times in clan reveal videos, where Florian did tell us that "this is subject of debate for now and we (meaning they ofc, seem odd to write it differently) are not yet decided how this will be in the end".Even if its only a very small risk that something they reveal now doesn't make it into the Beta, why take that risk?
Much better reaction, than silence ... since every reaction is better than silence.
As far as i know ... there will not be a demo.ask if there will be a public demo to download for free
Since last year E3, where was anounced the demo, and then canceled ... they let us know that creating (or polish if you wish) a demo is eating time, that they want to spend for game itself.
I was asking about it multiple times, here, on facebook, twitter, and discrord ... or maybe i heared it around here somewhere ... dunno for sure.
Especialy now, when they can just show us in stream how the game look after another half year of work, there is even less reasons for demo, since the employee that will show us the game, can easily play full game with doing just that much as s/he is allowed.
