For the record, it is strongly suggested that you don't kill them immediately or use more than 1 raid point on any boss. You get the same amount of seeds whether you do 1 damage or 1,000,000 damage.
Meaning, the more people who hit it, the more you can get out of the boss. This is also why some people are hitting less than 10k on a boss, so his hp lasts enough for maybe 5~6 people to get a hit in.
Getting fed up with people who go all out killing bosses even though it's unnecessary and it's just being outright inconsiderate. There's a reason why I only share to allies and not to the public. Any more of this bullshit waste of raid points and I'm removing non-rainbow players from my ally list. (Rainbow helpers get special priority just because they make my runs so much easier)
Hopefully others will do the same so those who go all-out will be alienated >_> so they actually learn not to be a dick.
edit: Also, you do NOT get any extra seeds for last hit. so stop being dumb.
