ATR is not melodeath, but metalcore. The Fall of Ideals was incredible (Mainly because of Shannon Lucas beyond-awesome drumming), but Overcome was a big pile of shit (Except for Relinquish, A Song for the Hopeless and
CHIRON . Havent heard the rest of them TBH.
Other melodic bands? Mutiny Within maybe, theyre extremely melodic; and if you want something kinda thrashier, you might find Soilwork good too: Start with their albums Natural Born Chaos and A Predators portrait (And if you want sth EVEN more melodic, hear Sworn to a Great Divide... I didnt like it though, its too melodic for me
). As for MW, they only have one full album.
