When Ghost Rider meets Storm, you get "The Tide Rider":

Would it really be that OP if triage beacon either provided better regen, a HoT, or maybe some degree of absorption to friendly targets in range?

No, it's a website.

Radiant Valor:

Well, a good majority of powers with a sleep component can be made to keep reapplying it, but the tough part would be to find ones with no damage component that would break said sleep effect. IIRC, plant and mind control both have AoE sleeps with no damage component, and mind has a ST sleep to boot!

Not your grandad's superhero, he's "The Ion Prism" (Elec/Stone Sent):

TBH, while I do like to vary the height of my characters, I find that going to either extreme tends to mess with the perspective while playing. I did try my hand at creating a rather small character who would don a powersuit while fighting, so she went from a near minimum female model to a max height huge one...

I'm offended by your attempts to not offend anyone!

While not a perfect solution, selecting something like "crystal minimal", along with darker colors, is at least less obtrusive. That being said, I would like a truly minimal or "No FX" option as well...

"The Inhibitor" is an archetype focused on directing enemy aggro via control effects. Basically, think of them as a tank that generates and handles aggro through the use of control powers. Their primaries would draw from the existing armor sets, but their secondaries would consist of highly modified melee power sets with a focus on applying or taking advantage of various control effects. This archetype's special effect/ability would be "antagonize"; For the duration of any control effect (applied by the Inhibitor), that enemy is taunted toward the caster and suffers both a defense and resistance debuff, due to them not being able to pay as much attention to attacks directed at them from other sources. The duration of these control effects would be shorter than their similar control powers, but generally the recharge times on these powers would be shorter, (to encourage a more active playstyle instead of simply applying an AoE and just sitting back to allow the inherent do all the work). I imagine the armor values being lower than that of tankers, but higher than scrappers. Similarly, the control durations would be shorter than that of controllers, and their damage would be similar to that of tankers. Adapting sets that have both a control and melee set should be fairly easy, (like electric control and electric melee), with outliers requiring a bit more creativity, (like illusion or gravity control not having a 1:1 melee equivalent). Similarly, I'm on the fence about whether to carry over taunt, or to replace it with a ranged control power and adding in the -range component...

Sure, but the question is whether their blasts provide enough additional DPS or utility vs what a controller's primary set has to offer...

How about an event where some "bizarro" copy of a zone appeared, (optional to enter, of course), where player characters are basically turned into plain old civilians, and have to try to get the attention of passing heroes, to save their purses from mean old Hellions and Skulls? All your powers get replaced with "call for help" and "hold purse really really tightly"...

I would never want to force the loss of travel powers on anybody, at least not in the main game world. Rather, an instanced event, maybe something like a giant hedge maze, could work...

Another idea could be to make level 1-20 IOs automatically attuned to the character, so they grow as that character does...

What if the base values of all IOs, (generic or set ones), never dropped below that of their level 20 or 25 equivalents?
