I suggest to use general macros for that not-too-much-communication in case one really is afraid of people disliking some advice.

At least the "<t>(which autotranslates a target's name) (Autotranslation)Attack<se.7>" which I'm using these days for Hard Modes has helped a lot at Ramuh and Levi plus isn't bound to a specific fight.
A "Hide!" with some se.-noise may also help in several situations.

And not to forget the legendary "You Comet Grraarrgh"-macro from old times, which is a must-have for LotA / this kind of battles.
