The most recent stat revamp has also targeted the Light, Rage, and Nature powersets, all of which have had balance tweaks without any huge function overhauls. Despite this, the developers are aware that several powers will undergo functional shifts and need a new set of mods once the stat revamp goes live, and players are assured that a system is already being put in place to address this. What that system is remains unknown, but it will exist.
DC Universe Online. This is not a complex or unusual concept. But for players who focus on powers or employ a hybrid style, weapon combos aren’t nearly as important. So as part of the stat rebalancing for the game, the developers had to find a way to make weapon combos useful for those focusing on them without making them overpowered. The solution is giving a scaling damage buff for combos over 2.5 seconds up to 4 seconds, thus meaning that long combos become far more useful for players relying upon them but short ones are still used for other functions.
