To counteract professions combining massive defense with massive offence, Ive been toying with an idea to make defense come at the expense of offence and vice versa.
If you place the agg/def bar at full def, you will gain the full benefit from evades and NR. However there are no special benefit by placing at full agg other than increasing your attack speed. And since all professions already get to have full attack speed while at full def, it looses its effectiveness. The proposed change is to make the agg/def bar more viable again:
If you place your agg/def bar to maximum defense, you will also get a debuff of your offensive modifer, regardeless what skill you use to attack, be it weapons or nanos, your offense should suffer if you are on the defensive. I would also like to see attack and cast speed capped at 2s when at maximum defense, regardless of attackspeed of weapon/nano.
If you place your agg/def bar to maximum offense, you will also get a debuff of your defensive modifier, be it evades or NR. Just like offense suffer from maximum defense, so should defense also suffer from maximum offense. At maximum offense you can attack as fast as the weapon/nano allows, and get a full offense modifier.
I think a change such as this could be a step towards creating a greater gap between offense and defense. Again it becomes a question of gain vs sacrifice. You sacrifice defense to gain offense, and vice versa.
