Start your sentences with a capital letter. End your sentences with a single period or question mark. Spell words out fully and correctly -- don't use chat-speak abbreviations like "ofc," and don't make up abbreviations like "smth."
seems like a bug. i just checked my logs from yesterday with logs from 1 and 2 weeks ago. all had roughly the same values for everything* (ofc, the 2 weeks older was sligthly under the 1 week old one, which also was slightly lower than the values of yesterdays log - gear/wpn changes ofc).
did you compare your logs, and did you see that bug on all bosses or just ones with gimmicks (eg. garalon legs, mel'jarak or smth...)?
* EDIT: comparing DS, Melee, HS, RS, SR, BB, ... values from DRW from 2 weeks ago, 1 week ago and yesterday
