I am not saying that the power isn't god, it is just that between how our power works and the QM statements I fell there is very small chance of a power as broken as that work exactly as we want it to and that even if it did conflict would adjust acordingly (besides this is one of those powers that make fights realy boring). But about C you are heavily averestimating bot us and Coil, on one hand we will have to do something to mess with his plots with some regularity before we enter his radar, it won't altomaticaly hapens as soon as we step out of home, also you have to remenber Coils power is strongh but limited, at the same time that he probably wont do an attack which won't succed the simple fact is that he only has two timelines, many plots and is trying to take control of the entire city, there is only so much he can divert at us and even less that he will , condintional to much he has to handle and how our action either hinder or help his plans, which brings us back to C, the only precog we may have to realy worry on the short term doen't realy operate like a precog most of the time ,won't come after us until we mess with him sonehow and will propably try to manuver around us first isntead of nuking us out of nowhere. Thus the more we analize the situation the more I fell it will be safer to all involved if we focus more on building a solid and useful base isntead going straight for immunity to everything and seeing how the QM works around that.
