As long as they also do it for others classes too, and that's what they might be juggling with right now. Reducing only the MRD atacks will cause a (justified) uproar because it will give the class a much bigger advantage. They will have to find a way to balance all cooldowns or find a tradeoff.
I recall you talking about something involving steadfast, how about 50-60%% cooldown reduction while in steadfast? They would have to make it so the timer resets if you break stance while on cooldown, else there would be possible mechanic abuse.
While we're talking about Marauder here, we have to take into consideration the other jobs; if there is a change suggested to marauder we have to make sure the change can be backed up with something else than "The job is broken and needs it" or "My feee~lings", else it's not gonna work. For example introducing double-attack on a Job related to Marauder is much more easy and in design than doign an exclusive reduced cooldown on MRD basic attacks. Would you be fine with the basic attacks have a reduced cooldown or weapondelay+x ... for all classes? I know some lancers and Pugs that would love to have their pierce/light strike viable again too.
While we're all passionate about this game, we still need to think with our heads, and not our hearts. Maybe I'm thinking like that because I do work in the video game industry and know how it is behind the scenes.
Current and coming mechanics (jobs), are also something we need to factor in and see possible avenues too (my point above)
Btw, props for making the effort to keep your posts as focused as possible, makes the whole debate more enjoyable and makes the brainstorming (because we are brainstorming, right?) more efficient.
