After reading some of the responses supporting the OP, I'm curious if you guys would be okay with a Paladin having a macro that says "PRAISE THE SUN!!" with some random sound and a big ascii sun every time he used Flash. Every. Single. Time. Or a similar macro for Provoke or any other spell or ability that's a regular part of a class's toolkit. I'm guessing no because that would be annoying as shit, right? That's how most people feel about text macros. They're pointless and annoying, but tolerable if it isn't something that gets spammed.

If it's a skill that you find yourself using more than once or twice in a duty or whose use doesn't really need to be conveyed to the rest of the group it has no business being in a text macro. If you absolutely insist on doing so anyway at least be wiling to change it if someone asks. Don't just tell them off or ignore them like the OP and then get pissed when they rightfully remove you from the group.
