Done the strikes for more than 2 hours..no key dropped...Angry like hell. After 365 all the drop will be garbage except if you have a key. Even with a key you still have to face the RNG. It will not guarantee you will get the strike specific item. Many people use 10 keys still did not get the imago loop or grasp of mallock. Even if we get it..the perks could be garbage and it just 2-3 light level higher ( contribute to 0.2 to 0.3 Light Level progress). Just make the key will always drop. We done the strike..just give the player award. Because even we use the key we still face the RNG and the contents does not always give us what we want.. Just give the key when its done..it will make the player happy up until they use it or make it RNG but when we use it will give the strike specific 100% (remember we still have to deal with the crappy perks)
