As mentioned previously, mod 20 was supposed to bring about some major gameplay changes (once again), but in a somewhat surprising move, Cryptic decided to just drop those on us early last week and without warning, with the actual new content being scheduled to come out later.
As is definitely a pattern whenever Cryptic changes the combat and/or stats, everything's kind of screwed up for the moment. My guildies and I did a Castle Never for the weekly challenge and suffered so many deaths, it was funny. You could argue that it's not a bad thing to tune the content up so that people can't just ignore or skip mechanics quite so easily anymore, but our group was between 30 and 40k item level, while the recommended minimum for that dungeon is 20k. No idea how a party with that would get through any of those fights.
Also, while my dps as a healer was never the greatest it's even worse now. I'll concede that healing itself felt better though, as damage was taken more consistently so that I could get into more of a rhythm healing it up.
On the plus side, Avernus appears to have been nerfed into the ground and we had a good time doing some hunts there. Just gotta sit tight and wait for Cryptic to rebalance things within the next couple of weeks/months - as usual.
