By the way, even if we was asking for GC estriction removal, the OP made another question,

To me the flat reduction of caster damage on crystal is a totally bad and lazy move,
if the "I'm DPSsing safe a crystal" is a real issue (I dont' think so but... ok), put something like:
"Magic Deflection: if you cast a spell on the crystal from too far (15-20y), a part of it will be casted on you too"
So it will be different mechanic, that in my opinion is bette than a flat nerf, for casters, similar but not identical to the ranged DPS reduction, and also won't affect DRK at all, because their range is anyway under that gap.

The reduction of the points needed to end the match is even worse, because you wil lbe able to full PvE a PvP match even easier now.
