I think Bozja was the closest to what I wouldve liked for relic.
1) Start off earlier in patch cycle and preferably on mid even patches, think mid odd patches for relic are just too late to be useful as an actual weapon...
2) Not tied to specific content, but rather having several options for each step, like what we got for some Bozja relic
3)Skipping/reducing steps after completing once and using previous relic to skip a step
