I was recently asked a question on whether a macro could be created to act as a countdown timer. Specifically, a scrapper wanted a countdown timer to let him know when unstoppable was about to wear off, so he could take the proper precautions before he was left in the lurch until it became ready again.
I didn't know of any macro, but then I thought of the chat bubble duration. I figured one could make a chat bubble, which was launched as part of a keybind for the unstoppable power, that said something like "US ACTIVE". He said US was active for 2 minutes, and so if one set the duration to 110 seconds, when the bubble dissappeared, one would know to be ready to run (or something).
I ran into a major problem with this -- the bubble duration appears to have a max duration of 20 seconds, no matter the setting. BIG bummer, since I thought I was being really clever....
Does anyone have any hard facts on this, or maybe a way to string a bunch of chat bubbles that fired one after the other, each lasting for 20 seconds?
