The main point that I never liked in these two techs is the fact that a unit loses its power to collect resources. An elite unit is capable of losing 75% of its collection capacity. It seems to me more like a penalty than a bonus.
Well my proposal is to decrease this penalty -50% to -30%;
Decrease the health gain to 10%. (20% health + 1 armour seems op);
Add crush damage for axemen.
For example, this changes should slightly decrease the strength of Ptolemies with rush of Hero + spam javelins + tech advanced.
Also decrease the penalty for a good rush at the start of the game.
