I do not condone kicking ppl over iLvl.
However agree, that opening dungeons of Heavensward should have minimum ilvl of at least Snowcloak (80).

Issue with alt-jobs is, that people have the dungeons opened from previous classes and level - especially dps - up to 50 with things like PoTD and then start joining Leveling or 50/60 roulettes.
50/60 specially will land them exclusively in non-iLvl barred instances like Dusk Vigil and Sohm Al, with the results descibed..
