News from the PTR. (these are not 1st April jokes like that ;p)
First of Season 5 is going to an end possibly as soon as the 14th of April, according to Blizzard. I let you conclude, like me, that we can probably expect patch 3.1 on the 14th.
Some more hard mode testing:
Iron Council on World of Raids, MMO Champion
General Vezax on World of Raids, same link as above
Hodir on World of Raids, MMO Champion
On the good news, all the bosses got more hp, and do more damage. they are tuning Ulduar up, and I won't complain of that.
No change about Holy Paladin Loot, the loot table stands for now (and is probably near from final).
