I'll give you the voice/prox chat but the DZ mixed arena is complete opinion (which had its own problems, tipping people off to our intentions). The rogue mechanic was very hit or miss for me. I'd prefer three options, PvE, PvP, and DZ. Sometimes we were in the DZ and just wanted to fight each other but the ramifications of failing when going rogue are too high if you just want to have a fun firefight with buddies.
I'm still not completely sold on the DZ, but I already like it more than any "social" or free-roaming areas (basically, areas where you can encounter other groups) in Destiny.
Destiny hyped up its social/community features, but it ended up being pretty barren. No chat is a big part of this, as is limited matchmaking (which is another area that The Division one ups Destiny tenfold), but there just isn't much to do in Destiny outside of actual missions/strikes/raids, and the occasional public event.
Last night, my group and I were forming vendettas against other player groups, thinking about ways to ambush them to get our gear back, etc. That type of social interaction simply isn't
possible in Destiny.
The classes; I had way more fun with Destiny classes/supers than I did with The Division. And yet to be seen on RNG; The Division could end up having horrible drop rates as well. Just because Destiny hid them under an engram mechanic doesn't change the root problem.
They play like totally different games, so opinions. Shouldn't really be compared except for how they handle the MMO-like aspect of social aspects and the end game grind/experience.
True, RNG is yet to be seen, but I like their progression system more than Destiny's, from what I've seen. I hated that Destiny relied SO heavily on RNG for its end-game leveling.
The Supers in Destiny are a blast, but I never liked that the classes didn't really have an underlying complementary design to them.
I also agree, they're very different games--but The Division already has a lot of what was missing from Destiny, for me.
