Some might say that spamming one Maplestory M Mesos skill all day every day is dull. So? Play one of these if you discover the one-key classes dull. People who picked the monotonous classes, presumably enjoy that playstyle.
Some might say that relying upon one maplestory ability is idle. Provided that spamming one skill on class A does not get you some better rewards than varying skills on course B (in terms of maplestory2 DPS or whatever else), why don't you allow idle people be lazy?
Finally, there is the dilemma of keyweighting. If it's possible to spam one maplestory ability all day, a stone could do it for you. But for this, there are other options, such as forcing movement after a variety of attacks. The sport already has that, it merely must make sure all skills are restricted in this manner. There's not any need to force people into playstyles they do not enjoy, simply to reduce cheating.
Bottom line: Trying to force the same alternating-skill playstyle on all courses is likely to buy Maple Mobile Mesos alienate a huge part of the game's players. I think it's a mistake.
Since my server has merged with another, I think our buddylist ought to be expanded to over 100slots that are +. I like to make new friends particularly when it makes the game much more fun to play with and less lonely but after the entire world mix, it is difficult to make any new friends since my buddy list has maxed out to 100/100.
