Lot's of stuff added to this patch, most notably is a complete rehaul of the city sieges. No more is it a flag dash, you fight for control points in Stage 1, Get super-sized champs in Stage 2 and then the King fight in Stage 3 with select players becoming champs themselves (super-sized as well!). All stages happen, regardless, unlike the previous version where the entire siege had to have 98% control (cumulative).

This makes the city more worthwhile than the empty sieges for Invader Crests unless their is a King push. Woot!

The Crest drops have been changed.
Ability to buy additional bank slots!

They did rush the BW and Sorc changes since they had a major effect on the city sieges. Their changes weren't slated until 1.3.6.
