Claudio QA in Polish and partial translation.

Nobody bothered to put it here so I translated the questions I have found interesting.
Q: Is Karax coming?
A: Karax isn't coming any time soon because he's somewhat replaced by Probius. We are thinking about him but no solid plans.
Q: Any changes for TLV?
A: I don't think so but I would like to point out we are working on balancing multiple characters. I cannot tell you anything concrete.
Q: Are there more multi-class characters coming?
A: Sure but not soon because they need a lot of balance work.
Q: Do you plan to add Overwatch maps with mechanics included there?
A: Definitely, Overwatch is an inspiration for us. We hope you will like what we are going to show you soon!
Q: Do you plan a Diablo anniversary event, something like Eternal Conflict?
A: Nothing of this scale but there is new content coming that is homage to the Diablo series.
Q: Can Probius retarget his photon cannons?
A: No but there's some sort of hero prioritising. I do not remember the details though.
Q: Do you plan to add King Krush?
A: It would be great but no plans for that currently.
Didn't translate them literally but the meaning is about the same.

Regarding multi-class heroes, it's correct translation that it will be a while before the next, but it's because we're digesting a lot of lessons learned from Varian at this point and the design team is considering how we want to tackle the next one. It is not specifically a balance concern stopping us, but balance is definitely hard for them too. :)

Replaced is not what I said, maybe came across in translation that way. We did not have Karax on the table and decide on Probius instead.
I mentioned that Probius has been on the list from many years ago, long before Karax was around in Void. We found a good time to work on him and a lot of people on the team are passionate about worker heroes from StarCraft, and a Probe is a natural fit since they can warp buildings in without having to spend time constructing.
