I can live without 'Control the pet'. Many macros can be more useful, like:

<t>, stop casting Protect when people are bursted.
<t>, check your gear, you forgot to unequip that lv.1 glamour item.
<t>, please do not spam Unleash for no reason.
<t>, nice 10 stacks you got. You have to let them kill you now, or they'll kill you last minute and we'll lose.
<t>, kite them, sprint, buy us some time.
<t>, please don't use Titan-egi.
<t>, you forgot fists/poison/attack stance. Please check it out!

Or, I don't know, just remove the chat restrictions alltogether.
It hurts new players more than helps them because they have no idea what they are doing wrong, and a few extra macros will not help them to understand this.
