To randomize teams is a good idea.
I would prefer to have flav and tiara, with a NPC to get the vouchers/medals, because otherwise there will be many afk chars....
hmm for banned skills may all skills which are banned in woe too? => Ice Wall, Basillica, etc..
Also i would prefer to WoE reduction because it would make bg more interesting
To get more people stay in BG i would items like OCA or DCA for vouchers.
Or Pots/Bombs/EDPs however Bombs/Pots/EDPs for a high amount of vouchers
