I also have over 1500 hours in Warband MP alone, and while I liked the customisation of Warband's item selection system, I can see that the potential of the Class system outweighs what was previously on offer.
Many of us have just as many, if not more, hours in Warband's MP Callum.
When I visit this forum, the common theme seems to be that any member who has come from a competitive clan, or played extensively, has an intense dislike of the current class system - other issues aside. It beggars belief that TaleWorlds spent time and energy in taking onboard the views of Warband veterans, and then threw it out the window for something 'professional'. I am yet to meet a player who actively enjoys the current set up, and who isn't endorsing a return to the original equipment selection.
Since you are here, or were, may we enquire as to what potentials you believe the new class system has over the original?
