Rei Control Mastery and Passives

Ok so, rei control governs one's ability to use their reiatsu and sense stuff... but any sensory techs you make before hitting mastered rei control falls under rei techs. That being the case I don't see why rei passives are limited to pretty much just sensing people when another mastery was given control over that from the start of the characters life. Especially when the guide says your reiatsu gains battle worthy properties at this point, and to be honest all I've ever really seen spec rei users get away with is different aesthetic ways to sense reiatsu. I don't see the point when the mastery already covers three different ways to do that for you and any other sensory tech you would have made would fall under your rei techs... or no actually that's changed now it's only under release. We have two different masteries governing something should only be under one imo, because I don't know why. I feel what rei passives can and can't do really needs to be expanded on as opposed to just "Here, you can sense stuff up 200m away in a unique way that no one else can," which isn't even true because as I said above any sensory abilities made before his mastered rei control just falls under a different mastery.

Anyways that's all I wanted to say.
