Vets melee power doesn't quadruple from their upgrades for only twice the cost - abit of exaggeration there, but yes the straight 50 koku for basic upgrades and 70 koku for token upgrades doesn't make much sense at all. Cost of those upgrades should be determined by things like the original cost of the unit, the unit type and the size of the unit - not a flat cost across the board for all units.
When CA swung the nerf bat many including myself had to delete units and regrind up again. I removed lots of units and redid new ones and 50 vet slots was always enough to field a 14k army back to back without being at any disadvantage. You're not fielding 20 strong vets in a 14k match, those 22.5k games are long gone.
I don't need to do any avatar resetting because I've played with 50 vet slots as have we all and that's all I about use anyway, actually alittle less. You can see that in my youtube vids as well as everyone else's that have competitive battles uploaded, which all show people using under 50 vets in their builds.
Anyway what Haze said and what I've said quite a few times on these boards since the release of the game ->
