so many people think that because you can switch your skills whenever you want, there will be almost no replayability. This may be the case, but with so many available options, it will take players time to get a good spec for nightmare, and really good spec for hell, and a perfect spec for inferno. even with the spec perfect it will be difficult to master it enough to solo inferno. the thing is that once you have u can take a challenge and change your skills to something else. you may not have to replay the whole game in a different spec but the hardest difficulty would be the most fun anyway, so why just grind through the first 2-3 phases just to get to the part where it is close to impossible to defeat the bosses with a second hand spec? thats just one class, there are 4 others to do all this with
