This PVE tier list looks like more a PVP tier list
I think Assault is a monster in operations and average in eternal war
Sniper is in his element in pvp but weak against the numbers of ennemies of the pve.
EDIT: I leave my noob comment here and wish to edit and ad a comment after few more hours. I understand now why Assault class is may be less effective than other in HL pve op' and I think sniper could be very good at max.
