It took a while to get the gear for, and do the old 40man WoW raids. No problem with waiting on the information, but the problem of the new weapons isn't so much for those that currently have R/M/E but those that are currently working on them. As just consider the amount of time and/or gil one spends on obtaining one, and will need to compare that to the cost of the new AH-able weapons. So if you were someone working towards one, where is the better place to invest said time or gil when not much has been said about keeping R/M/E relevant?
And I understand there are a lot of other perks to current R/M/E than damage alone, but when the difference is upwards of 100 damage, I find it hard to see the R/M/E keeping up. Compare Ryunohige's damage of 151 and all its effects to 266 damage polearm with the same delay. And Ryo was considered one of the best weapons in the game. Granted the 266 one is likely to be hard to get, but that amount of damage difference is hard to make up in extra effects alone.
