Valkrionn
The Hamster King
I have tried fawns. However at the exact same time for far cheaper technologies the Svart have their hunter, and the Ljos have their Archer, both of whom are very worthwhile to build, wheareas the fawn's charm has perhaps a 10% chance to effect a unit, is very expensive, and cannot best a warrior in offensive or defensive combat.
(unless of course fawn's have been buffed this patch. )
To be honest after my repeated negative experiences with them in previous RIFE versions I 've stopped building them completely.
Hmmm... Should be buffed a bit then. I like the role of the unit, as opposed to just a generic recon unit, but giving it more of a use would be good.
Good lord, don't remove the research bonus from Infused Ash. Reduce the slave % yes (or even remove it -- we can get by without it) but not the research.
The change that needs to happen there? Make D'Teshi-only improvements *only* buildable on Wasteland. Maybe drop the bonus down to 0.5% or even 0.25% if you must, but for the love of death don't remove it altogether.
Hmm... Having it only on wasteland is already pretty much the case, everything becomes wasteland.

And it is impossible to go below 1% on that tag.
I believe Valk has previously stated that the research bonus could not be lowered below 1%. Buuut if it is possible to grant a "hidden" bonus for every "x" ash obtained and then assigning both 1% buffs to that hidden bonus. It would allow for both effects to simultaneously be kept and nerfed.
That is far too messy.
One alternative: Have a building that requires X ash, that increases research? Would only be able to build one instance of the building for every X ash.
