Guild Wars 2

I am having a problem in that I am running a d/d thief who at level 40, basic double strike did 200 damage but now at 46 does 180. I have not changed weapons, armor or taken off any kind of buffs, so I am wondering why is it doing this. Is power like precision in that you need more of it as you level up to make up one damage point?

if you don’t change your gear every 5 levels you’ll find that you lose power/damage.
Damage is a complicated equation that is summed up by saying get better gear.

Hmm, I think it has more to do with the area you are in. When level scaling kicks in, it also affects your equipment.
A lvl 40 in a lvl 20 area wearing lvl 40 armor would be like a lvl 20 wearing lvl 20 armor.
A lvl 40 in a lvl 20 area wearing lvl 20 armor would be like a lvl 20 wearing lvl 10 armor. Or something like that. Also works the otherway around, a lvl 20 wearing lvl 10 armor doing fractals (scaled to lvl 80) would be like a lvl 80 wearing lvl 40 armor.

Are you also maybe fighting things with harder armour?

If you haven’t increased your damage, the tougher armor of your foes at higher levels mean that the numbers you see will be less. You’ll be emitting the same damage, but not as much will get through their armor.

Thanks for all the replies, so by the sounds of it damage is an equation that requires more power to gain a damage point as you level up. Which would explain why my weapons appear to do less damage as I gain levels that is my theory at least, can anyone confirm this?
