In my opinion, this loyalto-system is a BIG screwup in Biowares behalf. I'm on the final 3 missions in ME2 now with Jack's and Zaeeds
loyalty indecided. And i cannot do Zaeed's mission without either killing the civilians or losing his loyalty.. And after i help Jack, i can't break up
the fight between Jack and Miranda.. I have all but the final block of Paragon filled - and i still cannot pick certain paragon-choices, and that is BS.
I even went to the Krogan world and bought the deathmask for 10% conversation bonus... no change.
If i have enough Paragon/renegade points to solve a situation in the start of the game, the system should allow me to solve it in the END of
the game with much higher points ... but it doesn't . I've taken all actions as Paragon except for hitting the guy during interogation... and still
not enough points. The system is seriously flawed, broken and downright crap.
