Fairness aside, it is generally an unrewarding system for both people who get it quickly and for those who don't. For those who don't get it quickly, it's pretty self-explanatory. And being told to just go for the Leviathan/Coil weapons is no fix for the problem; it actually makes it worse. How? Novus. The next upgrade level was postponed, one of the reasons being that not enough people had Animus weapons yet - which is directly linked to those who've been unfortunate getting Atma, and those who decided/were told to just go for the alternatives. So those who DO have Animus weapons have just been unnecessarily halted in their progression, through no fault of their own. And as for those who have yet to get Atma weapons, once Novus is added, an already long grind just gets longer. Nobody really wins with the system as it stands right now, and even SE has taken notice of that.
