Trion just released their newest raid on the PTS waiting for the ascended to start testing it. This raid contains 4 bosses and 2 mini bosses. Naturally I had to go in and have a look and I have to say it's a beautiful environment.
Trion is also doing something new with this raid. We've seen "easy mode" in the past, but they're actually adding a new mode called "introduction mode". How this works is it buffs your raid's hit up to 1600 (regardless of where your current hit stands) and it decreases the health of the mobs as well as the damage they output.
We do know that it will drop raid marks for sure, but it's uncertain whether or not it will drop equippable loot in "introduction mode". Either way I feel like this is going to be a great catch up mechanic for guilds who are in a progression rut or just a great way to be able to have players that are behind current tier experience and enjoy new content.
I have a fantastic gallery of the bosses and the zone you can view if you click through to the post.
