How many chest exotic enagrams did you need from Xur to get Heart of the Praxic Fire this weekend? I bought 6 and no HotPF for me :( PS: Is there any difference if you open them with the class of the exotic you want? I opened them with a warlock, but I got just 1 chest for warlocks and 5 for the other classes Edit: Wow I am seeing a lot of 1's. I hate you all ;)
