I really liked and spent a lot of time on Mass Effect 3's multiplayer. There was some real teamwork required to make it past the hardest difficulties and almost all the available classes had some really cool mechanics and combos to them.
Even if the game was delayed for this, I'd be fine with that, because it can put a lot of value in, if they do it right.
BUT...
STOP with the RNG lottery effing microtransactions already. It's hilariously obvious why they put it in of course. They know some people will throw bucketloads of cash through the window just to get that one shiny hat they want, even if they have to open a million chests that contain nothing of value.
Even I got hooked and reeled in for a bit when the N7 characters were released. I wanted a full set of them and spent a good bit of money to buy a bunch of the highest-quality chests. Needless to say: NEVER AGAIN.
Yes I know you can keep earning ingame stuff to unlock them, but the MP isn't so fun that it's worth 1000's of hours of grind to me.
Give people something they are happy to buy and enjoy having once they bought it, not an endless stream of disappointing lotteries (for most).
