Please consider removing all the +x% Damage bonus from the relic completion bonus list. Not only is it frustrating to get, say a burn damage bonus on poison/acid relic or physical damage one on a cold based relic, even if its of the appropriate damage type such a small damage bonus is pretty much irrelevant.
Currently about half the completion bonuses for non skill bonus relics consist of these.
Considering the cost of crafting a relic having around a 30-42% chance* of getting a useless bonus for your build seems a bit much.
*I have used the completion bonus chances found at gracefuldusk to calculate this under the assumption that you would use at most three damage types.
