I don't think level 99 swords are absolutely necessay. I went through E-4 with a team of 88 and 89s, so anything about level 90 should be able to handle the enemies with ease. (I lost a gold troop in the boss battle and one of my swords ended up in medium damage.)

However, I do have to spend time and resources on repairing the damaged swords, so that may not be ideal if you're going to be grinding continuously. Also, I don't know if the level of the swords affects the drop rate.
