I actually must admit that the stats on runes are pretty decent. Reason I believe so is because of the joy from farming them. To relate, in the XBOX ONE game I play, Destiny, weapons stats were farmed to get a perfect set. In order to get what was termed "god roll" you had to go to a specific mission or play more pvp battles to get that weapon drop with the stats. Then, they released Destiny 2 and all stats on the weapons are the same with no rerollable stats. Since that change the game has become very stale. The issue I see with runes are farming higher tiered gears that do not drop any beneficial rune. An example is how the highest campaign missions where we get the highest drop rate of gear only drop blood, bolt, or rock runes. Rock runes I admit are useful, but blood and bolt runes are near worthless. In the current meta our heroes are dependent on ocean, flame, and river based sets. As I previously stated, runes need to be dropped in the slot category instead of the set category and also dropped in slots according to the specific campaign mission. I would prefer to get a left minor slot drop on 22.2 with any set than have to go to chapter 15 to drop my river sets.
