Thanks for the answers, now I understand pretty much everything ^^
Talking about healer, there isn't any member of the team that have any type of heal (exepte Celine but it's not really a healing spell), so I ive that role to Septim by giving potions to the others while they do the dps xD
About the grove xD I understand, I'll not complain anymore about it don't worry. Besides, in the end the path isn't really that hard once you know it, but the optionnal boss really caugh me off guard ! It was a real challenge, wich was awsome ! I have to use the ultimate spell of Morrigan to get rid of ot, it was epic, don't change it :D
About the "OoB old man bug" as I like to call it xD It didn't do anything more than just show the old man of Kara out of bounds, so of course it's a bug and it has to be settled, but it can be done later, it's not a major bug at all.
In the end it's a solid and encouraging update, and I more than excited to see what will contain the next one ^^
