Phalanxes too weak?

[Marquis of Roland]

Perhaps there should be a higher likelyhood of "Fighting to the death" when surrounded?

In RTR6 I've noticed surrounded phalangites fighting to the death & then routing if I open a gap.

I was fighting some gold chevron spartans, surrounded them with praetorian cohorts and they fought to the death.

Fighting to the death is basically a routing unit finding it has nowhere to run to.
