I think anyone that reads the forums much is aware of he problem that magica heavy builds are causing.
One of the biggest problems is caused by DK's being able to tank in light armor. If this itself was fixed, DK's would not be so overpowered.
ZOS clearly had a vision of what set ups should work best for each role, but the light armor issue is breaking it and causing huge balance issues.
Now people may try to say I should be able to tank in my light armor, it's play how you like here. Now that's great as a way to try and avoid fixing the issue, but ifs not true. If I want to be a healer, I sure as heck have to wear light armor and have to use healing staff.
So why is it not a problem that DK's can tank in light with a destro staff?
I think tanks should be guided to use heavy and shields, that should be the optimal set up for the guy that wants to take less damage.
Now for veriety, I would say make it possible in medium armor, but only with a shield. Or make it possible with any weapon, but only in heavy. That way it cant be abused like it currently is.
A set up of light armor and staff, should be the squishiest set up possible.
Fixing this would bring DK's inline without hammering those that are not abusing this.
