Guild Wars 2

I found that big problem happens with current events now days…
I have some time so I thought I will get some achievements (even this one that is repeatable – with bandit bosses).
People generally ceased to do it… they moved on.
These events are hard to solo.
Yesterday I had bandit that pretty much 1 hit KOed me – next one to Claypool.
Today I had Temvay the Aroggant (should be called the Annoying) -> super easy but, never stays in melee (as his “primary” attack is long dash), also if you try to range him then he also have projectile reflection just to annoy you more… I could solo it but it would literary take me 0,5h if not more.
Next executioner. He don’t bring any reward past first kill, so people who did it will simply flee, because he is no longer worth time spent to kill him. Killed him 2-3 times, and I no longer have any desire to fight him.
I just ask if we could have rebalance of these fights so group of 3 people (of appropriate level – So I don’t speak of people of lv 80 with best ascended equipment) could clear these encounters in respectable time.

People reported that other achievements (gathering ley energy by priority/consortium/inquest) are also badly scaling.
I guess at this point you could return to only spawning single energy orbs so only 1 person can pick it up.

Also tried to finish my Shatterer achievements, but currently if I don’t find community run, then it is impossible to break his bar (especially it is harder because there are people without HoT that cannot glide, and by this contribute to breaking bar).
Could we have achievement that don’t count on random people to get, like dealing dmg to Shatterer break bar.
