It never occured in my most pessimistic predictions we would only have one vote to decide two skilltrees, so I still cling to the hope there will be a second one.
If there aren't, well... Big disappointment here! i'm interested neither in Polymoprh that I still think people are getting ultra hyped about and having huge unrealistic expectations about what it will actually be, nor in Summoning Master because summons... meh.
I'm quite positive Bard would be second with a second vote and the reported votes of the 1800+ Polymorphers. Maybe it wouldn't be, but a second vote is still the right way to go regardless...
