The kindest way I can respond to any of these "buff the power sets I don't use until they are better than the ones I use!!!1!" is a gentle pat on the back as I murmur "there, there, it'll be ok." I think @Glacier Peak did a fine job of talking up the set as it is. I have it on very few of my alts, but those that have it use it very well and use it exactly as they described. Maybe, maybe there is a learning curve that some people may not be aware of? I know that's blasphemy but I can't understand otherwise.

Math-wise you get a lot more bang for the buck (and more drops) increasing your x rather than your +. Both help, but more enemies gets you stuff a lot more quickly. Try +1/x3 and see how quickly you go. then I'd try +1/x5, and feel things out from there. In my experience with melee alts, by lvl 40 I'm generally running +2/x5 and maybe x8 if I have enough Aoe. I'm at level 50 before I can blink. Also, the Experienced power (which is the same as Patrol XP) really helps a lot with rapid levelling. The devs give it out occasionally during events, but I get it mostly from opening hero or winter packs.

I'm seeing it as -150% for radiation v. -100% for bio, plus a faster recharge.

I'm tempted to make Pepsi Marlboro and see what happens.

Radiation Armor. Lots of debuffs, including the regen debuff from Radiation Therapy.

It can be. Some of my scrappers have at least two builds: one primarily for single hard targets and one for standard play (+4/x8 for me at endgame, which may not be for everyone). I'll usually pick a different power to put the Critical Strike proc in for each build. Also, look at Savage Melee set. Do you want to take Hemorrhage? Some people do and some people don't. It's great for proccing out, but if you don't want to use it it's useless. Also, are you paying any attention to the stacks of Blood Fury that you are building up? I'm not a pro on the set yet, but there are definitely times I want to avoid putting myself in lockout since I want the reduced endurance.

Most of my builds at this point run either Force of Will, Experimentation, or Sorcery. Unleash Potential is a catch-all power. I would like to 6-slot it if I can (Lotg +rech, Lotg D/R, Panacea H+5, Panacea H/R+5, 2x lvl 53 E/R DSO). On scrappers I've been moving towards Experimentation, since Moonbeam/Shadow Meld is such a good epic pool pair. Adrenal Booster or Corrosive Vial depends on how much AoE I've got. the pull power on Axe Cyclone now practically demands Corrosive Vial. I find Unrelenting ok, but not stellar. I'd rather have Invoke Panic!

I think it comes down to which AT do you prefer to play? For me, scrapper is more active. In order to get the most out of the build you will want to figure out where to put the ATOs in order to increase your damage. for a brute, it's a more straightforward smashie-smashie.

Not enough/too much cowbell.

Occasionally I consider putting together some art project where I would build a model of what the building would actually look like from the outside. Emphasis on occasionally and consider.

I try to diversify. I don't like pure defense sets, because sometimes defense fails you. Ideally (and this is for a scrapper), I will try to get around 40%+ defense to melee, 50%+ resistance to what I expect to fight against, at least one (and preferably 2) heals, and at least one "oh shit" button. For bio and radiation armor (which are admittedly my faves), this is pretty easily done. Since my defense is generally active, I can get away with not blindly softcapping defense. also, I like to put a LOT of knockdown and other crowd control, which helps with not needing to cap things.

Feel better soon!

Well, first of all it DOES do something. It restricts the highest enemies to their weakest attacks. How well would your character do if they were restricted to their weakest attack? I get it that endurance drain needs to affect enemies differently than enemy's endurance drains affect characters, because the deck is so overly stacked in our favor. Secondly, it is remarkably easy to build for endurance drain, significantly easier than building for health drain. You can drain a foe from 100 to zero in an extremely short period of time that is a tiny fraction of the time you can drain health from 100 to zero. If endurance drain immediately led to AV/GM incapacitation, then people would build for that. I think that people are blinded by their cognitive biases, and only judging by dps. Endurance drain significantly improves your survival (just like sleep, or -damage from kinetic melee, etc.) but people don't care because their survival is practically guaranteed and so they just want moar dps.

If you are playing a scrapper like you are playing a tanker (and by that I mean slotting any and all damage procs), you are not going to notice a tremendous pickup. Procs don't crit, and the parts of your overall damage that can be enhanced are minimal. Where you will see the most benefit is when you are at +100% damage from slotting, and using critical hits intelligently.
