What system are you on?
I am on PS4 and never had a single crash.
Had a single bug once that was fixed by reloading the last auto save.
You must be pretty lucky. I know quite a few people on the PS4 that experienced more than a few bugs, including being stuck in quests and not able to go any further, banter bugs, and so on.
Same with Xbox One users, which include myself. Thus far I have experienced:
Having to restart due to being stuck in a quest.
Having to restart because I wasn't gaining any schematics.
Dorian's quest not showing up
Solas final quest not showing up
Party members getting stuck in place or attacking air
Skipped dialog
Game freezes
Fade rifts not activating
Metals and herbs near rocks not being able to be harvested
Having a mage hat stuck on my head---when I was a rogue
Some bosses getting infinite health
And a few others. It's been good times. I never downloaded 4, I just downloaded Patch 5 today and already experienced a few bugs, but I am curious to see how many were fixed, too. I have already completed Dorian's personal quest ---due to a tip a wonderful poster shared with me on how to trigger it, so I won't know for sure if it's been fixed. Hopefully, I can trigger the Solas quest.
I know Bioware seem to be working hard to fix things, but I can certainly understand how some people, especially the few I have seen that have stated they haven't been able to complete the game due to bugs--are a bit annoyed that exploits that did no harm get priority, no matter the reason. I am sure it's frustrating for them.
