Looks like someone didn't get their happy ending and is now dissapoint.
I dunno, people say this a lot but I've not seen many people asking for a happy ending - just an ending that feels like it responds to the choices we made and shows us the consequences, both on the personal and the galactic level.
Except that didn't seem like what you are asking for. Or at least it didn't to me. Mayhaps you didn't word it clearly enough?
Does every choice has to have massive consequnces? Does every choice have to have a massive payoff? Does every choice have to immutable and unchangable by future choices? Does there
always have to be another way? (and if so, how many)
the answer to all above is no.
Sometimes, life is a b****. Sometimes things don't work out as you planed. Sometimes there is no perfect solution. Sometimes you make a choice to bake a cake, but then a future choice to use gas results in your kitchen blowing up. And no cake.
People think if the choice didn't pan out as they think it should, it is pointless/worthless. Yeah, I'm sure the krognan think curing the genophage is pointless just because the mass relays are gone.

Trashman why do you always make ****ty posts? 
Because I have to counter-balance the non-*****y ones?
However, if the roles were revered, and I was singing praises to ME3 and you were the one ripping it apart, you'd be still complaining....
