Why? It is really easy to get a ilvl 110 weapon now, sure it may require a few runs of syrcus tower, but the ilvl 110 soldiery weapons will be even good enough for Turn 9. For newer players it may be a struggle but running syrcus tower shouldn't be hard after obtaining relic and farming a few bits of soldiery gear..

Why does everyone have the mentality that you need 120+ ilvl to do Coil and 2nd coil.

The natural way of gear progression in this game from newbie to raid participate is pretty easy and short lived, you can farm an entire soldier set now in about a week including weapon.
