I think the idea of Berserker Roland would work best as a temporary class change in order to contrast his holy knight title with the class of a mad warrior. Having him being summoned as a Berserker right off the bat would feel redundant to Lancelot.

While unrelenting, super stubborn and glory-obsessed once in battle mode, Roland in his normal mood is a romantic and idealistic knight. It would work even better if he shows an outward personality of an idealistic gentle shonen protagonist at first but then breaks into his berserking form later.
