To illustrate these 2 points, I'd like to bring your attention to these newly introduced... artifacts
One per weapon, AND one per class item.
These are the rare ones, not INCOMPARABLE.
And yes, they bump up the
BASE (tooltip) healing or damage by a double digit % (if not triple).
Which makes them very popular in a certain category of
objective/competent/knowledgeable/commended players asking to somehow decrease the current creep healing and damage.
So, if it is the intent of SSG to keep such artifacts as they are, to introduce more of them in the future, in addition to the usual more-essence-slots, then there is and there will be a lot of bumps up to do creep side.
