Yes. There appear to be many that also share this sentiment. And most of them don't even post here on the forums, unforunately.
I came to SWTOR, looking for an in-depth RP experience. So far, the absence of chat bubbles has made RPing in this game nothing short of an impossibility. Therefore, i heartily agree with this petition. If chat bubbles are not implemented into the game by the time my time ends, i will not be adding any more to it.
Don't ignore us, Bioware!
It would be wise for Bioware to pay some attention to the issue and try to add an option to enable chat bubbles as soon as possible.
