I really have not heard the same results about Dragon Age's multiplayer. I have not played it myself. But, it just seems to be losing steam rather rapidly and people just aren't playing. I have no idea what went wrong there.
I've been thinking about the reasons for it, as others in this thread clearly have too. For me, a big difference was ME3's shooter mechanics. For one, the combat felt more engrossing (no auto-targetting). And it allowed for weapons to handle much differently. Compare to DAMP where any upgrades simply raise your damage output and sometimes provides a minor effect (10 % chance to trigger Mind Blast, or whatever). No weapon swap changes gameplay the same way changing from a Phalanx to a Scorpion does. Moreover, each Dragon Age class is restricted to one set of weapons, and it wouldn't make much sense otherwise, but it drastically reduces the amount of customisation and variety. In short, ME3MP allowed for a huge amount of different weapon and kit combinations, making it easy to 'keep it fresh'.
Also, biotic and tech explosions were just a lot more satisfying in terms of both visuals and audio, making it a lot more fun to change to a certain class that matched the kits of your teammates.
Another important difference is the unlock system. With ME3MP, you can't have a Mattock 7 already, open a pack and find a useless Mattock 2 inside. You always moved forward (or simply got consumables if you managed to max out everything except Ultra-Rares). DAMP, however, was very tedious in its colossal amount of useless loot. Sure, the first couple of games were fine, you would always get equipment better than what you started with, but the more you play, the higher the chances of getting inferior weapons. So the gameplay is less fun (subjective experience, of course) and your rewards become increasingly irrelevant.
I also felt the level design wasn't all that exciting. The idea of randomised areas sounds good on paper, but after a while I still felt like I was running down the same corridors and through the same halls, just in different orders. Whereas ME3MP gave you those moments where you're holding off in one room, you get overwhelmed, and you turn around and run away to that other place where you know the terrain will work in your favour, at least for a time. The rooms served a purpose in a way no DAMP room to my memory ever did.
What else... Yeah, I think those are the main points for me. Wait, one more: DAMP is more restrictive in what you can do on your own, making you a lot more dependent on teamwork. If your friends go down, chances are you'll die too. With Mass Effect, depending on your equipment and the difficulty level, you could be last man standing against a dozen enemies and you still had a chance if you played it well. I think anyone who's played ME3MP for some time has had those amazing moments where failure seems imminent... but then you somehow pull through and keep the mission going
with DAMP's mechanics you can't really take on that last group of archers, for instance, in some inspired way that prevents you from dying in two seconds. Or at least very few classes can.
Had it not been for my 500+ hours in ME3MP, I doubt I would've stuck with DAMP for as long as I did. I really wanted to like it after all the fun I'd had in ME3's multiplayer... but it's just too different. I quickly resigned to only doing the weekend missions, then after a couple of weeks gave up on that as well. In short, you're not missing out on anything.
I played Dragon Age: Inquisition MP only ONCE and I didn't like it. Purely because I knew from the trailers that it would just be people rushing to beat it, ignoring half the enemies and generally not even caring about team-mates.
That wasn't generally a big problem for the few weeks I played it, but I did have that one game where a level 20 Assassin joined our low-difficulty lobby and proceeded to just Rambo through the entire map. The rest of us got hardly any medals and we lost out on a lot of gold too because this person didn't care about treasure rooms. I remember soloing a treasure room at one point and I knew the Assassin wouldn't wait, so I had to do it before I was forcibly teleported away. I killed the enemies, approached the chest and... whoosh, next area. No gold for us.
Yeah, screw that.
Where DAI failed, I think, was in the fact that it was the end boss that mattered. Instead of ramping up difficulty, it just had an end boss... If you beat him, great. If not, well, try again. ME3MP didn't have that. Its levels just grew increasingly more and more difficult.
That's a good point. You worked your way up through increasingly difficult waves and although the wave 10 objective was the climax, trying to get a successful extraction was still a lot of fun (even before adding the extraction bonus). DAMP never felt quite the same way.
I think ME3 multiplayer was great and DAMP was not because one combat system is fun and inherently lends itself to multiplayer and the other is not and does not.
Obviously just personal opinion.
That's a more eloquent - and much more concise - way of saying what I tried to say above
I agree.
