Yes, we might already have seen the whirlwind blades and whirlwind axes. So when’s Funcom gonna add whirlwind fighting shields? 
The whirlwind fighting shields, of course will function like a pair of fighting daggers. Graphicwise this pair of weapons will look like a pair of round small shields, with a number of serrated blades as jutting out of the shields’ edges. Bonuswise these shields maybe can increase the armor rating of the person wielding them.
P/S : This idea came to my mind when I was browsing through images on the internet and saw an old picture of a Punjabi man wielding a serrated bladed shield.
If Funcom can really implement these shields, what’s stopping them as well to develop ‘whirlwind fighting fans’ too?
