Ok, all I gotta say without becoming spoiler-ific is the final boss is FREAKIN' CHEAP!!
"Difficult spike" does not do it justice... I was over-powered to a point that enabled me to literally one hit everything in the final chapter yet could hardly touch the final boss. I like the fact that there is some challenge here but while the rest of the game had me thinking whilst grinding, this scenario has me STRICTLY grinding. I also feel like the final chapter's maps were rushed in contrast to the rest of the game.
All and all I loved D2 to be honest. In spite of its apparent faults, it struck the right chords with me. But I WILL NOT defend the nose dive the final chapter takes. The main campaign is coming to a close that feels very abrupt and "out of place" IMO. Maybe I will feel wee bit different once I actually beat the final boss and see the ending but I doubt it.
