He Floweth Over (SR/Rad Tanker): A basement-dwelling 52-YO seasoned MMORPG gamer, turned superhero upon eating a strange pickle during an eating contest.
Rancher Joe (Demon/Cold MM): He grew crops and livestock until cheap imports ruined him. He turned to harvesting demons instead.
Get My Point (Archery/Tactical Arrow Blaster)
Top Thug (Thug/Storm MM): He commands a gang of politicians and spews hot air of his own.
SHUT UP WESLEY (BR/TM Blaster): You choose not to answer?
YOLO the Deranged (WM/WP Brute): A children's birthday clown turned evil.
I had a TW scrapper, and even when fully built I didn't come to enjoy playing it. I just couldn't get comfortable micromanaging the toon, especially with momentum timing being a thing.
The set isn't for everybody.
Top Thug (Thug/Storm MM). A politician and crooked as all hell.
Security (Bruiser)
Finance Advisor (Enforcer)
Attorney at Law (Enforcer)
Lobbyist 1 (Thug)
Lobbyist 2 (Thug)
Press Secretary (Arsonist)
But at the same time (at least from my observation), the stacked debuff appears more potent on the Core - higher debuff value per stack maybe? For instance, with the Degenerative Core equipped my Masterminds have pylons hovering between 20-22k Max HP when they go down, vs 25-27k max HP on the Radial.
I'm not familiar with Pain Domination, but thug-wise:
Soulbound allegiance: chance for Build Up gets the most mileage on the Bruiser. He already does a huge portion of your overall pet damage and this IO procs like crazy.
The Superior Mark of Supremacy ATO set can be broken up three ways to get three -10% recharge bonuses.
It's highly effective to frankenslot T2 and T3 with acc/damage IOs and damage/-res procs, and the Gaussian's chance to Build Up proc in the T2.
I recommend concentrating the pet +def and +res aura IOs in your T1 and Gang War powers. They both do low damage in the grand scheme of things and it'll free up room in your T2 and T3 for the -res and damage procs.
