personally i love all the new options

these are some of my findings:
* I use an Archmage now instead of a SS, because of the Book of hoeth item (great with ET magic)
* Gladeguard with trueflight arrows are amazing ranged (core). Always hitting on 3's!
* Silverhelms are amazing chaff/anti chaff/ screen (core).
2+ armor save (with the Fireborn rule they can't even be hit by Lore of metal).
* Phoenix guard are great, also for a mage bunker.
* Anointed of Asuryan in Exectunioners. He gives the unit a 6+ wardsave and +2 MR (so 4+ wardsave against magic) and ITP.
Which gives your Execs time to cross the table without being magiced to death. ITP also helps.
* Sisters of the thorn for life/beast magic (I still prefer Warlocks, but can be nice to have this option)
* Sisters of Avalorn / Waywatchers are both amazing ranged, but rare choice makes it harder to fit them in imo.
* Loremaster of Hoeth for having all magic lores. Seems overwhelming to me, but still a nice option.
...hope that gave you some ideas.
I also made an all purpose list for a casual ET tournament,
without Witchelves/Execs (my meta is bored of them, so trying something different with the new options)
It did very well (won 4/4 games). Check it out:
