I was curious as to what the highest number of achievements you can reliably have announced within a few seconds of each other is. Sweets, party, and drunk can easily be done with a few clicks at once to announce 3. You can do this right after finishing a "Legendary X" title to make 4 total. Is it possible to go higher than that without any noticeable delays in the announcements? Maybe do the first three after a vanquish and then instantly map to Cavalon/HzH for the savior title right after. Any thoughts?
EDIT: Secondary slightly related question. For faction/allegiance bonus weeks how does that stack with donations? For example, I donate 5k faction which gives me 10k title progression. If I donate 5k during the bonus week will I receive 20k towards the title track? Does the weekly bonus for this title also double up on turning in books?
