I noticed that my phaser power consoles are now #% instead of #a set number. Does this mean any more than 1 of that specific kind will have diminishing returns?
They function like they did before. Just now that the damage specific energy weapon skills have been removed, they couldn't have the consoles boost that anymore. So they just wrote 'em up as a percent instead.
Odds are, under the hood, it is just raising some hidden skill.
