What improvements are needed for the second iteration of Dragon Age Multiplayer?

Inb4Don'tHaveMultiplayer 

There's a pretty high likelihood for the next Dragon Age game to come with a multiplayer component; whether people want it or not. For those who didn't play it, DA:I Multiplayer was modeled as a dungeon crawler where you'd essentially play with predefined characters with their own origins, classes, and unique skill trees. While multiplayer in DA4 could be wildly different than this style of combat, this should serve as a baseline for we MIGHT expect in the next title.

In terms of what I believe the mode got right:

1) It attempted to add personality to our multiplayer characters, rather than having them be faceless soldiers with a few canned lines.

2) There was a greater degree of depth in each characters respective skill tree, and some characters - when outfitted with the right gear - had opportunities for multiple build options.

3) Keeping the game primarily PvE-focused meant there was more freedom to experiment with class abilities, kits, enemy types, and gear.

4) All things considered, it's a pretty chill game mode depending on what difficulty level you played on; and how geared up you were.

5) The Challenges system was a great addition, and gave you something to master and grind for; such as the banner silhouettes and titles.

6) The Prestige system was a cool concept, in theory, and getting a passive benefit for constantly playing your desired class preference felt rewarding.

7) Some of the live events were actually pretty fun, and helped in adding some lore to game; like the Varric tales (but I'll get back to that... >_>)

8) The various chest rooms having loot for you to nab was a fun part of the dungeon crawling experience.

9) Going for actual loot, rather than predefined gear (like Mass Effect), opened the door for greater build variety. In addition, improvements to perks on various amulets, rings, and weapons, made for far greater depth in player gameplay customization.

When it came to things the mode got wrong:

1) There was waaaaay too much of an emphasis on loot-box grinding. I know this has become a staple in the more recent iterations of BioWare's multiplayer modes (starting with ME3), but this one has always grated me; on some level. Having only a chance at getting something, rather than it being assured, will always suck to a degree. Bolstering this issue was the lack of intentionality when it came to how you could get most of the games loot. If the gear grind is going to be the prevailing reason behind why we'll want to continue playing multiplayer modes in the future, then I'd argue it's better to be generous and let us grind for various rolls on a single gear piece, rather than having us play nonstop for just one item. Speaking of loot drops...

2) Some of the drop rates for certain items were absolutely abysmal, and the requirements to even obtain some of these weapons were absurd. Most notable among these were the Hakkon weapons. While generally good weapons during the time of their release, the reduction in drop chance for each one you got (from 15% down to 2%) made it an absolute slog in obtaining them. Worse still, is that you had to rely on the Dragons Call item to even have access to getting said weapons, which you had to craft with materials you needed to grind for. It was RNG, behind a consumable wall, behind a crafting material wall.

3) Speaking of Dragons Keep (the map), that map was reused WAY too much for new, powerful gear additions. It got stale real quick, and having to constantly upkeep Dragons Call's was already a chore by this point. Tying into this would also be the lack of new maps.

4) Technical bugs and networking issues would often hamper the experience. And let us not forget about the infamous key bug.

5) Live events felt underwhelming at times, and some events never felt like you had a chance of completing them. Though it's been awhile, I remember there were multiple events where either Playstation or Xbox players simply didn't have the numbers to complete the objectives, and this would happen across multiple weeks. The rewards from some of these events were also underwhelming.

6) On the topic of the treasure rooms, while they were a good concept, locking rooms behind specific class types was a bad move. No one person (or group) should be punished simply because they didn't play with a class/character needed for each respective door. Had the game altered the room unlocks to reflect the class composition of your team, I think this would have been a better realized system.

7) There was a pretty distinct imbalance between each of the classes. The Arcane Warrior had to undergo several changes to even find an identity. The Alchemist, Hunter, and Necromancer never found any solid ground with most players (though I still liked both of them), while the Silent Sister and Saarabas were absolute powerhouses.

While the mode got better over time, I do feel like there was still some much needed room for improvement. I've got my own thoughts on what could be done to improve it, but I wanted to get everyone else's opinion beforehand.
