MechWarrior Online is being fortunately developed with an eye toward the fine details, as explained in the latest round of community questions and answers. For instance, the developers are designing LRMs to retain their intended long-distance functionality, with any missiles fired too close to the target simply bouncing off as inert duds.
The game is remaining very true to its source in many ways -- for example, location of equipment in a 'Mech will still play a major part in design -- but it's also changing certain elements. One of the team's major goals is to ensure that light 'Mechs are still a threat to assault 'Mechs, making sure that no pilot will ever feel as if his machine is useless in a given engagement. There's a great deal of attention to detail in the project, something that fans of the game should appreciate.
