As far as I'm concerned, I don't see a good enough reason to replay until major content is added. Don't get me wrong, I VERY much like the changes introduced in patch 5 (combat is actually not garbage anymore, dice rolls are more bearable), but the game in its current state is not that repeatable or long - 1 good & 1 evil playthrough, maybe reload important/interesting conversations to see other choices, try all the romances (which you can easily do in those two playthroughs, maybe just one, LOL) and that's it - and I've done that in patch 2/3. I have tried the druid in patch 4 (including the grove conversations) for a few hours and then the combat system (+changes such as rescuing SH) in patch 5 for another few hours and I just do not feel compelled to play EA anymore until something big is added (mountain pass? level 5? origin chars, I guess, although I don't like the concept).

If I strongly believed this will turn out to be a game I'll absolutely love, I'd be reporting issues and replaying it again and again (kinda have spare time for that right now), but as it is (a decent game I will probably 'like', maybe even 'quite a bit'), I'll rather invest my time into games I haven't played at all yet and play BG3 once it's released (maybe one more EA playthrough when EA becomes (almost) content-complete).
