They are "exotic", not "super rare". You misunderstand their purpose in the game. They are their to encourage different play style. I have played since beta on three characters, raids and nightfalls on all three every week. Last week I spent 160ish motes to get hopf and I don't mind it's being sold this week. I still don't have the 'Horn. But, "meh". The only "scrubs" are those that think gear they obtain through rng is based on some entitlement like skill rather than luck. You can increase your chance of getting gear by playing events that drop gear more often, but in the end, you can put the time in and still not get what you want, or by your standard, deserve.
