Guild Wars 2

Your first priority vs a necro is to kite. Second thing that helps is stealth. After that your direct condition removal is as follows-

Traited torch 4 removes 1
Traited torch 5 iMage removes 1 on cast, 1 on bounce (keep them up, that’s a condition removed every 6 seconds thereafter)
Arcane thievery transfers 3

That’s all I need and use vs necros. The rest is down to gameplay.

(These arent my current build, more condition damage heavy versions. But they’re both running traited torch and traited manipulations + arcane thievery)

Oh, one thing I should point out,
Clones not only become the target of necro’s skills/utils, but they also run around triggering them, which is good/important.

The other thing is, mirror images is a great utility for certain applications and builds, but the sooner you can master your clone generation and management, and move away from it to replace it with something else, the better.
