Let me tell you a tale of the Big Bears in the Hinterlands.
I had picked up Blackwall and after talking to him received his side quest to collect warden things. I geared him up, I picked his stats, then quick traveled to the Hinterlands, to the Forest Camp that was right next to one of the items. I was level 8, so I knew I'd be able to fight the big bears in the location. I thought maybe I'd run into two.
Boy was I wrong.
Right outside the camp was the first one, fighting an outlaw. I took them both out, then went around the corner of the hill to find a path up to get the warden item. When I found one, I climbed the hill only to be greeted by a big bear charging down it. I was forced to the bottom to fight him. Took out the bear, started the climb again only to find ANOTHER big bear charging down at me, with a outlaw partnered with him against me. Took them out, this time cautiously went to the top of the hill. There was a random Ram that popped out of the ground, but luckily no bears.
I picked up the warden item, turned around to go back down the hill, and wouldn't you know it. A big bear was waiting at the bottom for me. I fought the bear and as soon as I finished it, ANOTHER big bear and outlaw team came down the hill. At this point I thought, screw it, run for the camp, quick travel the hell out of there. There is a certain point enemies will stop chasing you, which worked, but there was ANOTHER big bear & outlaw fighting next to the camp. I thought maybe if I ran through to the camp, the NPCs there will help me fight the bear. Unfortunately the NPCs are not programmed that way and walk around oblivious to a big bear ripping my companions guts out. I couldn't quick travel away because my companions were battling the bear, but I did discover that I could still rest and regain health and potions that I had lost fighting the 5 previous big bears. The bears health had a dent in it and my team was fully healed, so I figured I could take it out quickly and leave.
WRONG.
When I got my inquisitor positioned, and turned my camera's view, there was another big bear coming around the hill aside the camp, between the two boulders. I just un-paused the game to watch the beast body slam Vivienne and then claw the rest of her health away in a matter of seconds. At that point I just gave up and waited for the bears to eat everyone so I can just exit the game to get away from it for the rest of the day.
I have had groups of Templar's and Mage's spawn on top of me when I was just standing around trying to figure out where to go, or listening to companions talk.
I've watch numerous fennecs, rams, & nugs appear and disappear like ghosts.
I've found camps of random NPCS sitting around a fire, only for them to magically disappear into thin air once I get close.
The templars and mages random spawns are annoying but manageable, the random animals and npcs are amusing, but my god, those big bears!
I'm loading up the game right now and the game's last auto save is at the bottom of the hill with the warden item not picked up yet. I feel so sick to my stomach right now and I'm bumping the game down to casual from normal of all things, cause I just don't want to deal with it.
edit: bumping it to casual sort of helped. no bears came at me on the hill period, but when I got back to the camp, three of them tackled me at once. The one I expected to be there fighting the outlaw, the second one that comes around the hill, and this time a third new one that came up behind me.
edit 2: Also, they are Large Bears. Not Big. Not sure if there are Big Bears in the game, just in case to avoid confusion if there are.
