This actually is a pretty good idea. Since some spells, when used by the team that goes first, devistate the 2nd team more. These spells include beguile and dispels. The team that goes first doesnt have to worry about losing pips when dispelled, or attacking their team when beguiled. Even if its like 1/4 less points lost, it would still be a good idea.
I also favor the team that goes last should have an extra white pip at the start of the match along with one stun shield. Also that the first team should not be able to see what is cast on it during the next turn in terms of beguile, dispels and the like cause they can always get around such spells while the second team can't.
I agree too. One time, I was in a 3v3 team and a death person on my team beguiled there storm and then, it ended up killing that whole other team. I like that happened but it was not fair to them.
