Rapid Solo Suggestion...

I am a severe altaholic, tons of toons, none at 50, it's a sickness.

Anyway, I'm really interested in trying out the Arachnos soldiers and Khelds and such. SO I know I need to get something to 50.

What would be a good combo on each side, to get to 50 with minimal fuss and maximum haste, i'm not trying to spend a lot, I just want to rocket something on each side to 50 solo.

If you wanted to burn something to 50 alone, what would you build?

Scrapper or Brute, Fire/Regen or Fire/WP

Blueside pretty much any scrapper pairing (nods to fire/wp and spines/dark) and redside any brute (ss/wp, ss/sr) or MM (bots/dark, thugs/dark, thugs/poison) will get you to 50 in short order.

I would stay away from /SR if you want an easy time. SR is by no means an easy build to grind to 50. WP is grind easy.

Another for /wp.

As much as I love my /sr characters, and I have 4 of them, my kat/wp was the smoothest run from 1 to 50.

Plant rad/kin/storm troller

Redside there is no substitute for bots/traps. I was soloing +x3 by 24 and x6 once I hit 32, with an IO build that cost me about 10 million at 25 with IOs added as I get slots. Its faster than anything else because its got ridiculous AoE and even more ridiculous survivability.

Blueside, a fire or claws scrapper with regen or wp will be the easiest. Shield defense is also great if you can get someone to level you up into stamina levels, my fire/SD scrapper tears up the world now that he's got stamina and room for a few attacks plus toggles and the end and slotting to support it.

If you're on a populated server, you can get just about any controller up quick as well, as a decent support toon never lacks for teaming.

I recently heard someone suggest a claws/elec scrapper for this.. Myself, i'm levelling a spine/WP at quite a hefty rate. Some teams cause them headaches, though; the ones where you're surrounded by /regen and /SR scrappers and blasters with maybe a defender or two, mostly.

For speedy levelling the entire way, Claws/WP brute. The only problem there is that you'll hit 50, go to make your shiny new widow... oh look, more claws.

For fast, fun options that won't put you off playing with the best of the veats. Fire/Dark corruptor, Bots/Traps or Thugs/Traps mastermind, Plant/Fire Dominator.

I don't know what to suggest for heroes really; khelds don't really seem worth grinding for. Fire/Rad controllers work nicely, as does Ill/Rad, and you can earn your place on most teams post 12 with a Kinetics defender even if you do nothing but speedboost and heal.

The best thing about these options though is that even if you hit 50 and find you don't like khelds, they'll still be worth having.

Another nod to Fire/Regen, Anything/WP Really nothing's ever going to slow you up, and you have the boss killing ability necessary. You just want to GET to 50 so end game IO'ing isn't all that important. Those play very smoothly, Farm style area builds usually require time and money to surpass something like Fire, because taking down a high level boss and several medium sized spawns, and reaching mission bonuses and story arc bonuses quickly are the ways to level fast solo.

willpower scales up better than regen, regen gets quick recovery at level 8 and click heals. You'd likely level up faster and enjoy it a lot more if you teamed, then just pick whatever.

Likely candidate also, Dark/Shields when Shields first came out that seemed to be the only set with absolutely perfect synergy, I figure siphon life would get you over the hump dealing with shields un IO'd defense, but I've never played shields outside of teams really until IO'd up.

Another vote for Fire/Regen scrapper. I have one and he has been the absolute fastest to level 30 I have ever gotten, and I don't see him slowing down much into the 40's.
