The important message here is easily said: I really liked the Halloween event and would like to see that variant of dominion implemented as a permanent option.

It changed the game flow quite a bit and allowed for some pretty suprising come backs. Point B felt a lot more important, since the minions were so strong. You could not just kill them off while walking by.
Thus, the other two points became more like gateways to conquer B, because you needed them to get the buff. I liked the structure that dynamic gave to the matches.

At first I thought that would cause a rich get richer situation, but the changes to the way you earn points seemed to balance that out quite nicely. At least the matches I was in were almost all very interesting and thrilling from start to finish.

So, good job! I think you are on to something there. I, for one, really enjoyed my time with the event and would like to see that Dominion variant return.
