dude,
the only point you made was about PoW
If you wanna include PoW reward, need to agree on that first and then start discussing where it's gonna come from
1) no need to change the ICO. its ok as it is.
2) No need to give AGRS for free, it's interesting enought, so just buy them
3) 2% inflation is not necesary for itself
what i have in mind regarding pow is to have a "miners tax", a dynamic percentage that'll be used for mining reward, to be able to be changed with time. unlike implicit tax-by-inflation like in bitcoin. but that's only my personal opinion -- we'll do it all over tau.
