Indeed. I have no problem with the endings other than that there's no balance. For my renegade playthrough, it's great. Spoilt for choice. Paragon-wise, it's deeply unsatisfying. They're just poor choices. Sacrifice is fine, but it's what goes alongside it that I don't like - Control, synthesis and destroy all have their problems.
And of course, the lack of a "win" ending just grates.
The endings are just too heavily biased towards depressing.
