So, after having taken some time to absorb and study the changes, I am interested in my fellow players thoughts on the Ynnari changes.
First off, I do want to say I think as a whole for the game this is a move in the right direction. Ynnari were stupidly powerful while forcing a rather single type of build (more on that below). I feel the changes have helped to mitigate their build as well as their power, without completely gutting them. Without field testing though, it is rather difficult at the moment to see where they really fall....
Quick summary of changes and thought:
Strength from Death: I like that this applies to pretty much every model now. The first part of it is a bit meh imo, but if you can get the +1 to hit in cc, which is pretty easy to do, there are a good number of units that enjoy that. A big win for me though is the relative ease by which it is triggered and the fact it applies to your whole army when triggered. This allows for shooting units to set up their melee counter parts, which I really like the feel of.
Characters: Not a lot of real changes here and the points staying the same on the Yncarne really blows (imo s/he is over-costed by 87 pts), but the real gem is being able to take the Ynnari HQ's in any Eldar detachment and not have the detachment become Ynnari nor give up their bonuses. This has really helped DE especially with 3 new HQ's to help flush out double bats.
Stratagems: There are some decent ones in here, and some meh. Overall, I like the direction taken but I feel they are a bit light. To me, the strats are the tool set you use to adjust and adapt, and Ynnari loses some flexibility here. They keep some stable Eldar strats but don't gain a ton of new toys. Standouts to me are Ynnead's net, Reborn together, Back from the Brink, and Exalted of Ynnead.
Warlord traits: There are some beautiful traits in here. I think these were very well thought out and I am looking forward to what combos I can make with these. Lord of Death and Warden of Souls are the two that immediately speak to me. If master of Death proced on a 6+ to hit, I would be more inclined but alas, it is not so.
Relics: Again, a bit light. The sword is quite nice, especially on an Archon or Autuarch - this can really do some damage. The Pistol is decent but doubt I will ever use... I think the real winners are the shroud to make some one pretty damn tough to kill, or the locket to make a hero (cue music now).
The winner to me is a Skyrunner Autarch, Fusion gun/Reaper Launcher, lance, and Banshee Mask. Giving him either Lord of Rebirth or Warden of Souls (leaning to the latter) and the Corag Hai's Locket. Let him finish off units with his shooting to boost his attacks, With Warden of Souls, it has 5 str 7 attacks, going up by 1 each time he kills off a unit in CC or shooting....
Overall, I think Ynnari definitely got knocked down a peg, which was needed, but I think there are some interesting combos to be used now and perhaps some units that don't normally see play may get used.
