Eyonix posted some news about the changes coming with 1.10, many of which are just amazing! Firstly the new Tier 0.5 item sets are explained a little more, and secondly dungeons are now capped on players. Hurray!!!

The existing level 60 instances were mainly meant for 5 players and seem WAY to easy with a 10 man group. This change will force players to play the instance at the intended dificulty.
