Spoiler I did as well (full paragon about 60% renegade) and saved the base for Cerebus...to me it seemed to valuable to let go. While I agree with what Legion said if humanity destroys it...it will be free to forge their own destiny/technology. However, I eventually believed Grunt was right...sometimes in war you gain something from the enemy that is suicide not to try to capitalize on. While humanity could get "cursed" by inheriting the Reapers technology...I personally think what could be understand Reaper tech thus neutralize its advantage...not base all of our future tech on old Reaper technology. If ME2's ending choice (saving the ship or not) has the same effect (no pun) that ME1's ending choice (saving the council or not) had on ME2 (which was like none) then it won't really matter. I really wanted to blow that thing up to be honest with you. Like the thing with the 2nd genophage...ME2 did a great job (with characters and diaglog) of actually persuading me to change my mind....and I'm open minded...but like I very stick to my principles.
