While I agree the range should be brought up, people cleared all content on week 1 with all jobs so I can't believe this is to be an actual issue.

My static has a Nin and a BRD and we cleared E2S on week2 with no dps issue (, and had we raid 2 more days the first week it would have been a week 1 clear)

So, yes they should be buffed, but any party not bringing a range because of that 1k difference isn't worth much.
If your group just has every player at 40% perf that should be enough to get a clear on any boss, especially with the 460 weapon
