The augment system is one of the few great changes that DDO saw last year. I would like to suggest the addition of Yellow Augments (common) that the players can easily find in treasure with Healing Amp. The augments should be something like ML5 10%, ML 15 20% and ML 20 30% for either Healing Amp or Repair Amp. Not both combined though.
Healing amp and Repair amp need to be added. The game only has (had) a few ways to incorporate it previously. Convolessent was removed from the loot system, 30% heal amp only shows up on 2 pieces of Level 20 gear and there are no places to find 10%. All of these sources of healing amp are obsolete now.
