Make sure you follow the directions when setting your zero stop, particularly with the screws under the turreet cap. DO NOT remove the screws and only loosen them to flush with the top. Tightening them is also fairly critical, where you want to use the allen wrench (short end) and not over torque them.
Honestly, I was never one for a lot of "clutter" in a scope, always worried about task saturation. However after shooting and hunting with the MOAR, I found it wasn't the problem I thought it might be. I do not have the level system, so I've never used just the marks and prefer to dial. Your future testing of it will be interesting. Please report if you do.
Illumination adjustment could be easier, but I set mine once, just very low, and its a non-issue after setting it.
