We're doing some Rogue stolen power updates that will launch at the end of the month, focusing on creating more options for specific builds. You'll see more powers that talk to Max HP, Max Spirit, Movement, among others.
As part of that, I'm pushing to retrofit the Support category over time. Depending on how things go, we may end up making this global and adjust all Supports to fit into the new style to some degree. Colossus and Juggernaut will be part of the first batch. These will now be toggled powers (can only have 1 active) that add a secondary resource bar and new mechanics to Rogue.
Juggernaut's adds a mechanic very similar to his Momentum, building up as you move and spending to amp up the damage of certain powers, such as Blob's Belly Flop. Colossus' simply adds his Armor mechanic straight-up, which replenishes when you use Dive Bomb. However, these come with a trade-off. Colossus' will be replacing his total defense and deflect rating bonus multipliers - these were a result of a global change to certain properties, and ended up making this power way too strong, even with it's dodge chance reduction. Part of the design of Rogue's passive or pseudo-passive Support powers is that they all have a unique affix that can't be found on any other passive. The defense rework made that not the case for several powers unfortunately, and this will rectify that. Both total defense multiplier and total deflect multiplier are still available through other stolen passives. In regards to trading off functionality for these newfound mechanics, Juggernaut's, as a toggle, will lose its on-demand invulnerability, but will retain the on-death invulnerability.
Ultimately, the goal here is to make the Support category more defined and interesting, leaning it away from steroids and more into toggles.
