Are Lvl 5 Units viable anymore?

[ckdamascus]

Without Rune Mages (Crossworlds version), seems like there is no way to resurrect Level 5 units easily besides Turn Back Time and maybe Gift (not sure how it works or if it works on Lvl5).

I'm still somewhat early stages of the game (lvl 25) and playing the Viking class.

Lower level units, IF they can get the +60 attack over their defense, were the most damaging units in the game, so it seems fast Lvl1-Lvl4 units are the best choice since they can be resurrected en-masse via paladin.

A real shame as I was one of the first guys to use the Shrek Build (giant) in Crossworlds.

For people who are further in the game than me right now, is Lvl5 unit availability and viability better/easier?
