It seems that most folks aren't discussing the changes; either they like them or at best they're tolerating them for the upcoming racial past life grind.
The ultimate issue is most of the changes are still lackluster and leave human as the top-dog go to choice; especially once players have the +10AP from 'racial completionist' by doing every life.
Warforged/Bladeforged: The changes here were mostly AP cost reductions, small quality of life, and a nice new T3 and T4 option for regular Warforged.
Half Orcs: To me the changes here were perfect; it breathes new life into a race that is almost new used save new players.
Half Elf: Overall this one is nice as well, although I'd love to see the dragonmark improved as well. Give the DC's on Electric Loop and Call Lightning Storm proper scaling based on charisma score and player level. Additionally; update Power of the Storm to be a toggle in line with other racial weapon damage effects. Allow it to scale with melee power or spell power and call it a day.
Dwarf: Remove the Dragonmark requirement for the new and improved Hands of Stone, or separate it from using Dragonmark charges and turn it into an SLA similar to the Drow treatment in this pass. Also lower the Dwarven Shield Mastery cost to 1AP per rank.
Drow: Solid changes. Only improvement necessary is double checking that Drow Venomed Blades actually scales with melee power. As the tooltip for this one has been out of date for a long time, while the Assassin version notes the scaling.
Elf: A nice quality of life bump that affects all races that share the Nothing is Hidden ability.
Shadar-Kai: Yes, all of my yes. I've wanted the chains to scale properly for a long time now, and now you've given it to me. Worthy of a few testing lives for builds using the chains in Reaper.
All in all; the changes so far have been great quality of life updates. But for the most part they leave the situation as we started. Most people will play humans; either for the extra feat, visuals, or frankly that once we've got our racial pastlives done, we now get the best benefits from the racial tree for free.
I think the best addition at this point without coming up with completely new ideas is to follow the rumored and suggested ideas by Severlin a year or two back to add the other racial prestiges. If they follow the example of Elven AA; and cost a total of 14AP each to get. This would open new build options for certain race-class combos, without creating massive power creep. Ultimately I think giving us the trees will create better diversity rather than the return to mass humans you're going to see once the racial TR train is finished by the majority of the player base.
