- Added pets to the new raid unit frames when displayed in party.
- The default UI Scale has been altered so it will be set at a 1:1 pixel/texel ratio. This will result in a smaller UI appearance for higher resolution monitors.
- Players may now adjust the local "Lag Tolerance" time for better precision of spell timing. This is an advanced-users-only feature found in the Interface Options (Combat) panel
The other, more interesting, part of the patch is 'Elemental Invasion P4', where every couple of hours 2 cities from each faction are attacked by elemental forces and you must defend them and then enter a portal to defeat 1 of 4 bosses. This event glitches very often, but as far as i can make out it goes like this:
When the event starts the earthquakes in each of the cities get more frequent and guards start shouting for citizens to leave the city, after a few minutes everyone is called to arms to install 50 barricades in the city. Once this is complete elemental rifts will spawn in the city and you must kill 32 mobs for each one before it is stable, there are about 3 rifts per district and 7 districts over all. You must also free trapped citizens in each district before it is secure, once all 7 are secure then you may start the 2 boss encounters for that city which you can enter from portals at the front of the city or with your Dungeon Finder.
The cities which are attacked on the alliance side are Stormwind (Water and Air Elementals) and Ironforge (Fire and Earth Elementals), for the horde it is Thunder Bluff (Water and Air Elementals) and Orgrimmar (Fire and Earth Elementals). After you have killed the Elementals in each city, as mentioned before, you will have access to the 4 boss encounters which will drop one IL 251 each. This event will also give an achievement called 'Tripping the Rifts' for helping to destroy one of each of the rifts, this is a limited time event so i suggest you go get your cheeve now! ;)
