you'll get used to the positonals, ... up to the point, youll even miss them a bit in fights with no positonals.

when "learning" postionals, it can a bit much (especially mnk), ... or be annoying in dungeons when adds & bosses keep turning around (like in the lv 69 dungeon), ...

but once you got the routine (muscle memory) down, those postionals become real fun part of the rotation, even if occasionally there are moments of annoying adds or bosses that keep turning (those annoying adds/bosses exist for all clases, in different ways), ... dont give up on "positonal" dps!
