Scarlet Shocker

Much of the answer that works for you is going to depend on your own goals and personal playstyle If you're soloing, XP boots "take the edge off" the levelling process. If you team, they do the same but you typically get more XP simply by dint of being able to knock down more enemies in a given time frame. As others have pointed out, Inf gain is negligible (I don't usually start filling slots until close to 20 unless something useful actually drops) just vending everything that comes my way. My own preference is to not use an XP boost, or at least only use a little one (25% or 50% max) but sometimes I do use 100%ers, for example when I am already familiar with the powers and style of a particular alt and I just need to get to Level X. Some of the lower level content is outstanding and well worth playing through as intended and an XP Boost can break that experience. The main reason for not using XP boosts is because you might get to 50 very quickly and then discover you don't know anything about the game.

Overpriced, huge marketing budget, no real talent behind the skilz, but a lot of social media Basically BrewDog for zombies.

... life is just too much to bear sometimes

now, Who would that be?

That's fair enough but I kind of feel that Action Jackson is more... blaxploitation kinda thing... much more punchy than I see with the toon you've posted. That is not to say you're wrong, in any way. It's how we are both seeing a thing with different lenses. I think the outfit is really great but for me personally it doesn't fit the name. Somehow, I'm feeling there's a discordant element there but hey, that's me, and this is your character so I hope you find something that fits.

I've never played one, but I looked at the images and see "melee support" so I'm thinking somebody who is 2nd line, gets in there to biff the enemy behind the tink, but also lays down some solid controls and some handy buffdebuffs. I'm thinking Dominator with Energy Assault component and a primary powerset that doesn't have too many obvious "power FX" - so not ice, or fire etc. Maybe Arsenal/EnA or Mind/EnA... something like that. One thing I'm not clear on from the OP's original is what is his name? I am working on the presumption it's not the OP's forum handle but knowing that might give insight into his raison d'etre

Regeneration only works if you have a Doctor.

That's their Away strip

Don't limit yourself. Play all the things

Experiment: ATs, Powers, Pools, APPs, PPs, Blue, Red, Gold, Marketing, AE, creating, playing, vending, flipping, defeating, killing, switching, EATS, VEATs, zones, arcs, SFs, TFs, content, PLing and all the rest of it. You'll find something you like

Scarlet Shocker was my 2nd toon, born on Defiant back in 2006. She was always an Electric/Electric/Electric blaster even when blasters were pretty well obsolete but when I came to Homecoming I remade her on Excelsior as an all electric Sentinel. There's a Scarlet on every shard, just cuz, but that one is by far my favourite. I much prefer playing it, easier to play, more resilient and the slight downturn in damage output is a small price to pay. so I totally get the OPs PoV

Disconnect time can be a problem in other ways too. My Ice/Time corruptor is now just an Ice/ corruptor

I like the concept of this pool and some of the powers. One of my bigger concerns is the vulnerability to certain powers, which goes against most of the game... as others have pointed out they kind of mirror and reflect existing powers but put them in one box, but how would these pool powers stack with other powers from different sets, and how would they stack with other players carrying them?

Teleport, Combat TP and Hover probably all suitable to get around, as in blink in and out. Gravity and/or Storm if you're a Poltergeist and throw shit about
