I don't believe I ever stated that the Bard was brought in exclusively for the Healer Limit Break. What I said was that it will be losing some of it's versatility in certain situations... such as when Titan EX kills both healers, and all you have left is your bard and 3 bars on the Limit Break Meter...
I would also like to point out that the Bard is going to be losing a really
HUGE aspect of its support capabilities in Heavensward when it loses the Healer Limit Break. Instead it will be using a DPS-oriented Limit Break from Heavensward forward, which while that seems all well and good, it will limit the Bard's usefulness in certain situations.
This makes it sound like that it is a very important feature to bard. Even in titan EX, a healer really shouldn't be dying unless its a botched landslide (in which case, you can't res them anyway). Even then it's only one fight, it has almost no utility in coil fights where one death can ruin everything (t10 for example, and you're more or less going to die anyway because of the animation lock), or they died to
Also... is that your signature that is making it look like I have a gnat crawling around on the inside of my screen?
