After playing a bit more with the patch, I can now say that you did good work on this Crate. The only thing I miss from GI now are the monster names on top of the healthbar and text version of existing buffs/debuffs with CD but I can live without those. As it is now, the game is enjoyable as a vanilla experience. 
However, I’d like to post feedback on Invoker changes. I’m not a fan of PRM myself (because DW guns are more fun) but from my experience, it really needs all the bonuses from set and supporting items to give it some much needed punch. The skill as is doesn’t really hit that hard for a 4-node skill. But if that is the will of the designers, then I can accept that.
What I’m not a fan of is changing the conversion on Invoker Blaze. It fundamentally alters the devotions and secondary mastery you select for the build. When you look at the old Invoker, you get to the conclusion that you focus on lightning because that’s where most of the conversion is going. The magehunter version is not going to be affected much as it supports all elemental damage. But what about this build? [Druid] Invoker's Fury [v1.0.0.6 HC]
Yes thats a vanilla build. But its not far fetched to imagine vanilla PRM druids would migrate to the Mythical Invoker version when AoM came out. Lightning is strongly supported by druid and so they have no problems focusing on that while treating fire as an extra. The shaman side of druid has nothing going for it outside of Wind Devils RR in terms of support for fire damage. With the recent change converting most of the damage to fire and coupled with the nerfs to totem and maelstrom, I don’t think I’m being dramatic when I say druid PRM is now a dead build.
