house of wolves disappointments

the house of wolves exotics made me mad today because i got the ram only to find out its perk has changed from activating radiance from beyond the grave disorients enemies to another useless void walker exotic :( why did they have to change it now purifier robes have its perk, which again had a better perk to start with the Ram does have a few things going for it though 1 it looks awesome 2 it focuses on melee which is great for me. don't get me wrong its a great dlc but the perks got ruined why!!!!!!!!! ( still not hating its just that i spent 92 motes of light on helmet engrams only to get what i thought was a good exotic for sunsingers. now i have to buy starfire protocol (still its a good exotic though) Post if u have/ had similar disappointments
