I know I brought this idea up before, but it was in other threads and it was usualy lost admist the mediocrity. We all understand why SE is reluctant to increase the number of lines in a macro, as it would increase the likelyhood of botting and/or RMT activity. This is a very valid concern for them. Oh the other side of the coin, I think they fail to grasp the significance we place on the ability to condence macros that swap gear for such-and-such reason. So my idea, my "fix" that will adress SE's concerns and get us players what we want is as follows;
A Toggle Switch.
How this feature will work is that each macro will have a botton on it that toggles it from the standard macro to a 16 line macro.(Yes a 16 line one, don't be afraid of the size SE.) This now toggled macro will have pre-assigned(And undeletable.) at the start of every line the command text /equip. This will enable your toggle macro to be used for gear and gear only. This will invalidate for the use of other command macros and help players to further streamline their ammount of macro space.
