I didn't say ilvl sync created challenge, what I meant is the challenge is already there, but people either skip or ignore it, it wouldn't happen with ilvl sync.

With the HP of an i80 caster dps they can barely take 1 hit from the last boss of SV HM, 2 hits meaning death, that alone would force people to pay attention and dodge, same with the debuff applied by the second boss of hullbreaker. For Amdapor the fight turns a bit harder when DPS are i55 and they have to break the healer out of the prison ASAP. And so goes the list.
