Method 1: Complete a turn in coil will 100% give green coil gear loot while the blue one will have like 1% drop chance (like back in 1.0 or maybe the % was lower) and remove the lock out. And after new coil come out the green item will be remove and the blue will be 100% drop rate

Method 2: the way it is now

With the 2 method I mention above, I would take the method 1, no lock out and just spam the run
