Been thinking some more, and I've sort of constructed a timeline or sorts.
October 25th until October 31st:
Every now, parts of words seem to vanish, making it sound like words get cut-out here and there. Separate letters vanish rather often. Letters can vanish every other sentence, words only rarely vanish entirely.
November 1st until November 7th:
Complete words get cut out now, people aren't able to finish sentances or they lack words here and there. Light interferance. Letters still get cut out here and there, but clarification is still possible.
November 8th until November 14th:
Sentances break up often, though a second try should be able to fill in further details to clear communication up. Long conversations will give minor headaches.
November 15th until November 21st:
Severe breaking up of sentances, key words faltering. No ability to repeat communication as too much tries will result into IC headaches.
November 22nd until November 28th:
Single vague words that are very quiet. Users will experience chaos in their heads and migraine-like effects when speaking to it.
November 29th until Cataclysm release:
Complete gchat inactivity.
It's just an idea and the things work for both speakers and listeners. Feel free to do things your own way, and alter things where you find them most rewarding for the RP that goes on.
So yeah, just an idea. If we're going to do this, might as well put it in GMOTD or guild calendar as well.
