should this be more common with teams?
Probably depends on how much spare cash you have lying around. If you have multiple teams in other games that can also benefit off it.
Is having them very ingrained to your team even a good thing or would an external perspective be better for someone in such a role.
At the end of the day hiring a full time psych for 6-7 people is probably more expensive than just having the company fund sessions with an external psychologist when appropriate.

psychologist can't really help if you have a bum ass team tbh
