Upgrade or alternative upgrade?

1st level: the old upgrade is better – because it’s better. 2nd level: the new upgrade is better – because there’s no penalty for shooting. 3rd level: the new upgrade is better – because we hit twice. 4th level: the old upgrade is better – because it takes off well and hits much better afterward. 5th level: the new upgrade is better – because there’s a blinding effect. 6th level: the new upgrade is better – because it pierces through stacks of units like a dragon, and also has a charge attack (I’m not sure, but the old one seems to have it too). 7th level: honestly, I’m not sure here. Fallen are a good class… they restore life, but Arch also has a good resurrection ability, which can be used for various strategies. I don’t know what to choose here, but I guess I prefer Fallen. Vampire, after all.
