I understand why a Sentinel and Guardian would have at least one similar skill tree, cause they come from the same teachings and pretty much had similar training. But a sith marauder and Juggernaut come from a polar opposite background. There should be no reason why these classes of warrior would be similar in any way shape or form, they fight different, think different and have completely opposite belief systems. This can be said about all the other classes as well. just voicing my opinion
