I don't mind the transfers, what I think needs adjustment is balancing, or more specifically, the cost of raiding. Currently it's easy for a small tribe to quickly prepare the gear for a raid for a pretty low resources cost.

I generally play solo PVP, and even though I only have a small base and a couple of tamed dinos I still get raided often. I would guess that it's usually a net loss for the raiders most of the time because as a solo player I don't have that much cool stuff or resources, but it still happens pretty much once a week. I feel like raiding needs to be more costly. It will make little difference to big tribes because resources are easy for them to get, but it will prevent smaller tribes and solo players from constantly being raided because the cost vs the reward isn't worthwhile.

For server transfers I don't think it would hurt to have a cooldown between transfers. Maybe players can only transfer once every 24 hours and creatures once a week or something like that, but I like having the option. I would hate to have a scenario where the server I'm playing on becomes crap because of griefing or duping or whatever and I don't have the option to move, but I think limits would be a nice middle ground
