Sounds like you are posting this in the wrong forums. I am quite sure that the SC2 developer team is different from the WoW developer team.
I’m not sure if I am right about this - that the Support team and the Developer team are separate from each other as well. They might talk to each other, but they won’t pick up each other’s work if it doesn’t come from the right channels.
If you have opened a ticket, you should be able to return to see that ticket on the ticket submission page (while logged in). Otherwise, then you probably did not submit a ticket.
Lastly, it really depends on the content / nature of your ticket. Know that SC2 is a decade year old game. For it to even have some form of Support is a miracle in my opinion. So if it is something that is a real bug / issue, they may take a look at it. However, if it is something that isn’t really relevant (e.g. please change the storyline), then it is a waste of people’s time to even address it.
