Low level Shaman dot damage.

[Crenshinabon]

Just wondering if everything is correct. The P1999 wiki says the dots should be doing more damage than they are actually doing.

Level 9 dot does 8 a tick max.
Level 19 Affliction does 6 a tick... which is pretty bad for a 19 dot.

It could just have been like this in classic. Not sure exactly never played Shaman.
Anyone here know if this is right and working as intended?

This is all pve on the pvp server.
