Since you rounded down 1.5 skills, I selected 2 skills sets.
I actually would like Anet move away from e specs as only thing being able to define class mechanics and rework trait lines to have Grand trait line define class mechanics and sub trait lines be whatever else. So you'd have Mesmer duelist, Mesmer dominator, elemental arcanist, ranger beast master, ranger skirmisher, yadda yadda.
