4th Horseman is the only exotic weapon (other than the PoE weapons, not going to get into those) that eludes me. Curious to know- where did yours drop for you? I have seen quite a few drop in Strikes, but never for me. Looking to narrow my search...
(I realize it's all RNG, but for some reason certain weapons seem to drop in certain activities more than others.)

First one ROC strike, second one lvl 28 POE. It was the guaranteed exotic for the first run.
