Well, to be honest, more classes are super useful (archers, keepers, elems, arcane warrios, legionnaires come to mind), but the whole MP is unbalanced. I mean, come on, there have been what, 2 balance tweaks to classes since the release (nerf of the Reaver and boost of barriers, lol)? ME3 had weekly !!! balance changes.
Guard should be buffed. It is using the SP mechanic, when its strength derives from one's armor rating. And barriers should be nerfed a bit.
- More maps
- More enemies (darkspawn, carta smugglers, anything)
- The option to fight dragons (either by adding them to the perilous roster of beasts or create a small new map for just them)
- The option to choose your enemy
- More expensive chest with guaranteed better loot, guaranteed rare loot for community challenges and rework the RNG ridiculousness
- Change the item lvls. Instead of getting the same weapons (that are useless and will be salvaged) do it like in ME3 - if you get the same weapon, it is improved. So you can work towards the goal of getting everything and not depend on sheer luck. Ofc this would mean a change to the crafting system would be required (mats could drop from chests directly)
I am sure I am forgetting something, but this will do for now.
And for crying out loud BW, hire more people to take care of the game post-launch (both for MP and SP), right now it feels like there is only a skeleton crew left.
