the only problem i’d see in that is the cost for relics being made even higher to compensate the increased chance of a gold (and lets be honest nobody really wants a higher price). it’s what happened with character relics when the percent chance for that character was made 100%.
maybe a slight boost in the bonus relic would be nice though. the last 10+1 pull i did i got all bronzes. it was pretty disheartening.
With the introduction of Gold and Silver relics this past update, I do not think they need adjusted at all. The shards in time will balance it out for you if you have this terrible luck not getting golds in my opinion.
