Even with level 60 i still see ppl get hit by landslide.
You just need to get good/ not suck and have a decent connection so u don't lag etc or whatever and die to every possible aoe.
But the key here is to get good.
Its just like the current primals.
A bunch of ppl still haven't cleared bis ex but have been trying for days/weeks. Just get good then join an actual "clear" party and not get carried for once.
