regarding the question whether followers develop together with the main character (that means level up etc.) I read quite contradictory things. Some state that followers level normally, comparably to the main characters. Others related to some bugs. What is really the case?
I almost suspect that there is indeed some issue. For example, when I received Lydia as my follower (I am quite still in the beginning) I was level 13 and she fought quite fierce during battles (including these neat finishing moves). Currently I am 19 and she dies much quicker. So, using the console command "getavinfo health" I was comparing level 13 (I reloaded; and level 19. And indeed it gave me the same information (current health 216). Am I maybe interpreting something wrong?
Another question relates to follower tactics in battle: many times I can′t hold back my follower (for strategic adjustments). So for example I summon a fire rune on the ground. Instead of waiting with me behind she runs right over it. Is there some way to control follower behaviour during battle?
Best regards,
