Expedition's Challenges is impossible

Hi , some of Expedition's Challenges is impossible for melee character to do , 1 exemple is "Defeat Uhtred , Coventous Traitor without any player colliding with any Seeking Star" . The Seeking Star alway chase player and it move too fast that make impossible for melee builds to dps boss and avoid Seeking Star at the same time . Same go for "Defeat Vorana , Last to Fall without any player being hit by any collapsing Orbiting Stars or their projectiles" .Pls fix it and some other boss Challenges .

For Uhtred, it is hard yes. You have a much higher chance of completing this by doing it on lower ilevel logbooks. Or you can put a portal before entrance and log out if things are becoming messy and you are unsure, then log in again and wait outside until you are collected again

For Vorana, you dont have to worry about her attacks, just keep your eyes focused on those orbiting stars. or you can adjust and give yourself more damage and try to kill her quicker than usual.

The Vorana 4th condition is near impossible to do in high-zone levels. I get it, you are supposed to make the orbits pop and not get hit by the projectiles in the meantime. Might sound like a great idea on paper, but here is the reality:

In three out of my four attempts the boss spawn location was near a out-of-bounds gap between two "islands" connected by a bridge. Even though the boss circle was ~90% in bounds, those orbs in the black fog were not, making it impossible to deal with them. Eventually I got overwhelmed and hit, failing the condition. In the fourth attempt the boss spawned in the most krangled space possible and the spheres spawned behind a wall out of sight and I got hit since I didn't see the sphere spawn (or shoot).

Seems like somebody designed those challenges in a vacuum.... frustrating as heck.

Edit: So I bought a logbook with vorana (zone lvl 69) and just nuked her, managed to get the challenge that way.
