Well funny you should say "back on topic" Vayne...I was thinking about this tread and oddly enough...it was about the OP so I decided to take a little break from WvW and go into Orr to see how I feel about it. Turns out I can beat a single risen (whatever) with about 90% health and not a single utility skill used. Veterans with mobs are harder (used 1-2 utility skills" but not a big deal to kill those mobs as I run along.
Last thing I tried was to solo that champion tall guy thing...that has grubs..but as a DD elementalist that's a bunker spec, I wasn't doing enough damage and more and more grubs kept showing up...but I didn't die...I just kept healing, doing damage, kill most, they respawn, heal, do damage...this went on for like 5-10 minutes so I decided that with my current specs I would have trouble killing a champion solo but I should have no issue running around Orr and worrying something will kill me. And since champions aren't really meant to be soloed (esp as a cloth mele player) I personally feel like Orr is just fine because it should be challenging as a lvl 80 zone but otherwise, I never felt in real danger. So if anything it might need to be SLIGHTLY tougher but that's just me.
Granted I'm maxed out on my gear.
