I think they would have been fine if they just kept the 2 members they fired on the team. I even enjoyed Abrahadabra although the guest vocal tracks (except Gateways) kind of got on my nerves because I like ICS Vortex's vocals so much. In Sorte Diaboli (if i spelled that correctly) is my favorite album but honestly, i like all of them except for this one and Stormblast isn't that great because of low production value and most of the songs are in a language i don't understand.
