Why change the name just because one person has left? Did Lynyrd Skynyrd, Black Sabbath, Pink Floyd, Alice In Chains, Megadeth, Metallica, The Who, AC/DC, Judas Priest, The Temptations, Crashdiet or Faith No More change their name when they replaced members? Some of these have just replaced lead singers others (The Temptations, Lynyrd Skynyrd, G'n'R) only have one original member, there's also Napalm Death that has no original members.
