Id say it should be alittle different.
Its not like I spend 2 months to get a suit and weapon of Ogh and that suit and weapon plays for me better then I can play myself.
Time investment should be like making Ogh, spend ages and gain something useless unless your good enough to have use from it.
Now imagine if a White bear would tear tamers face off in seconds like they do to Ogh wearing super soldiers.
I would also add that you should have to stand up in its face and any interruption should auto fail the taming as in you or it gets dmg, you move away, turn to quickly etc.
Now that would warrant White bears to be as good as they are currently
oh how tamers would cry rivers
