I don't know why this was removed, you really just can't use it anymore while you are engaged in a fight with multiple people around since it is unprotected and suffers greatly from the point-of-origin bug so when you do get CC'd out of recall there is a very high chance you get warped back to where you were recalling from. Awakened Hashashin also eats a lot of stamina while not having dedicated i-frames so it was really useful as a disengage without eating half your stamina bar. For example, you were able to place Hourglass of Defiance before engaging then able to do a basic purge->ridge->sand warp> collapse->condemnation-> Hourglass of recall and you were fine. Now, you have to spend either shadow slicer, silent breach, or paradise surge to get out which is incredibly painful since they are all either gapped, have high stamina costs, or have long cooldowns.
Please revert the change. Return the I-frame->SA on recall. At the moment, it is just a niche party trick for juking people off cliffs and cheesing points in RBF.
