What if they added a weapon that was like a pole arm or halberd that had a very long reach, attack speed of about the brandish line, and damage output of the DA GF line. To balance it perhaps it would half your shield strength or negate blocking all together?
On the shield side, I think it would be interesting to see a shield that gave gunners some type of bonus like the BTS or maybe a shield that was like the chaos set which gave you big bonuses at the cost of resistances and possibly health.
Don't give them ideas.
I can already picture the Tempered Calibur and Great Defender reskins now.
How horrifying.
