Epic Pool Recommendations

I tend to like to go thematic when I can but I sometimes make exceptions when the idea really works or I want a specific mechanic.

Necromancy/Dark Miasma Mastermind Hero - If I were staying with hero pools for this one I'd probably pick Chill Mastery since cold is often associated with the undead.

Dual Pistols/Traps Corruptor Hero - For this one i'd either go electricity mastery or power mastery. Elec gives you a nice hold and has some thematic resonance with tech type characters. Power is generally good as a default when you cant decide. It's especially nice since it gives you power build up for some strategic damage or +special boosting.

Storm Summoning/Sonic Defender Hero - Again I'd go with elec or power. Both seem to work thematically and both have useful tools to choose from.

Kinetic Melee/Superior Reflexes Scrapper Vigilante - I dunno here... Body mastery is always my "go to" when I can't find something I like thematically for scrappers.

Ninja blade/Ninjitsu Stalker Hero - Hands down weapon mastery It gives you some thematic coolness like shuriken and exploding shuriken and some nice passive buffage with physical perfection which you get to take as the first choice.

Super Strength/Willpower Brute Villain - Most people like the soul mastery PPP for brutes cause of gloom but I personally would prob go with energy mastery for thematic consistency though mace mastery might not be so bad if you want to incorporate some "mace play" into your character concept.

VEAT Fortunata tract Villain - Honestly? As a veat you don't even need to take a PPP. You have a huge selection of abilities to choose from in your primary and secondary. Add to that all the supplemental options from regular pools and I can't honestly see anything "vital" or thematically appropriate outside of maybe Soul Mastery (I always seem to associate the widows with Ghost Widow).

Plant Control/Fire Assault Dominator Villain - with a mix like plant/fire I might go with Ice mastery and not because sleet but because thematically you could go for the "elemental" type character mixing plant fire and ice. Not that plant is actually an elemental type but it gives you a broad spectrum "natural forces manipulator" kind of vibe. Alternative you could go with fire and have a kind of "solar power manipulator" theme where you use that power to enhance plant life to control. I used a theme like that with a plant/thermal controller.

Electric Blast/Devices Blaster Rogue - It depends on the origin here for me. If you're something like mutation where the blasts are generated naturally as opposed to say tech where they come from some super powered armor, then I'd prob go with elec. It has some great tools to improve a blaster's survival and works thematically. For a tech based "super armor" kind of character I'd be torn between elec or munitions. both have some great mez options and munitions has an aoe snipe!
