The Endless Excavation one will help with getting more runes too.
How? I only see an increase of relics one gets.
The Tome and Abyss look quite interesting too me. The Excavation is maybe something for players who use spells a lot (probably not many)
Needles of Tempest ... hard to tell yet, since we don't know how good the fairy units will get and if one, or both are short ranged,or if an upcomming archer upgrade will make 'em useful again.
Atm I see a big problem with so many wonders and so less shards and now with so many wonders so less KP too.
For example to get the Tome to 11, for it to produce 3kp/day one needs sooo many KP and shards... it will probably pay out in the long run, but there are other wonder too and more to come... so it get's a really tough decision what to build and what not to make a good use of 'em. Especially when there are wonders like the Needles, of what we can't really tell the future use.
Having (almost) all wonders would be nice, but to make them effective one needs 'em at high levels....
