Solo Defenders - What Difficulty Settings Do You Use?

I'm currently running the same as you at +1x6 on my traps/elec after IOing my build up a bit. Before that I believe I was doing 0x5.

I'm pretty sure I haven't touched the difficulty settings so they will be at whatever default. I will go IG and check soon. Shame I can't level him any further at present

i usually leave it on the base setting with bosses added until the late 20's on most of my Defenders, but my mid thirties Traps/Dark is more about +0/x3 w/bosses. My Dark Miasmists are far more likely to run at x4 to x8.
For more single target focused secondaries i'd go more +2/x2 to x3.
For my FF/Rad i just generally avoided soloing. i should dig that one up sometime and try her again in this new age of IO's and more granular difficulty settings.

Back in the day I would always set my Difficulty to at least Tenacious at level 10. I felt that if a character could not at least take on a Boss solo, that it was a bad build and I either worked on the build or abandoned the Power Set. I never got that far, though, even my FF/Rad Defender was able to get through the Bosses with a combination of Detention Field and Snipe and Retreat tactics. Nowadays (at 50 and pretty nicely IOed out) he solos at +2/x1 or +1/x2 levels easily.

I honestly stay away from most of the possibilities of the new system, just trying to set to something like the settings of the old system. Guess I'm just comfortable with it. It is really nice to be able to lower difficulty to -1/whatever to overcome tough EBs though.

On average, I consider +1 x4 with Bosses to be hard.

I run anything from +1 to +2 with x2 to x6 with Bosses. Remove the bosses and it is often too easy, although much faster.

Even my worst solo-er tends to breeze through +1 x2 with bosses, only slowing down for endurance issues.

I run a Dark/Dark Defender, currently level 35, and im using SOs.

I solo at a difficulty of +0/8 to +2/8 depending on what im fighting, and yes, these difficulty settings are with bosses included.

When I get my Epic Pool, ill most likly jump the difficulty upto +3/8 w/bosses.Then after I ding 50, ill IO up and max out the difficulty setting to +4/8 w/bosses.
