@GML- I think you are underestimating these powers GML. From all the games I've seen (Frontline Gaming has been playtesting them against top tier tourney armies) they are obliterating people. Thunderwolves moving 60" a turn and assaulting, ignore cover, ignore LOS pulverizing the cheesiest Eldar armies, its certainly brutal stuff.
On the contrary, I am not underestimating these powers at all. Take a moment to read through the
write up I did on the powers. Based solely on my years of gaming and the abilities of these powers, I am more than aware of how powerful they can be. But out of 28 new spells, only three of the powers are strong enough to say that you desperately want that - Electrodisplacement, Phase Form, and Shifting Worldscape. If you look at the three most popular core disciplines (Biomancy, Divination, and Telepathy), they each have two spells that are must haves for their impact on the game; two of those disciplines give them as Primaris powers.
I'm not trying to say that the powers from Angels of Death aren't powerful. They are ridiculously powerful to the point where they are, at the very least, equal to Invisibility as the go to power that everyone wants to get.
These new powers completely throw that tactic out the window. In fact they throw most of the core rules right out the window. They are very extreme powers and I think they warrant a lot of concern.
I know this is splitting hairs, but the only core rules that are "being thrown out the window" are Line of Sight from Phase Form and being able to cast inside of a transport with Technomancy (which makes sense for a discipline that is about affecting armoured units). You could make an argument towards Shifting Worldscape as well.
Now, you made a point about top tier tournament armies being thrashed by these powers. I don't watch battle reports nor do I compete in the very top tier of tournaments (like Adepticon or ETC), but could you elaborate on how those psychic phases are going that is allowing such domination? How many dice are being used to cast some of these spells, how many are being used to deny? Are the marine players trying to cast more powers than they are able to (I keep bringing this one up because it is a common mistake that I see)? Are these examples being set up to show the ridiculousness of certain powers or is it happening within the natural flow of the game?
Even better, do you have a link to where these reports are so I could take a look?
