Set armor requirement for techmech

[Prog]

The problem here is that the Tech Mech will follow damaged tanks straight into the battle if you’re not looking at it all the time to stop this behavior. As the Tech Mech is a fragile unit, it will die quickly in battle for the cost of the invested 350 gold. Disabling the auto-repair will prevent the Tech Mech from running into death. The drawback is the additional actions you will need to give orders manually. Nevertheless that is not that big of a deal, as giving the heal command once is enough to order the Tech Mech to heal the targeted tank/structure completely.

That is straight from the guide.

It's not a big deal [the techmech is safe from death] the person says. Then nerfing the evasion and magic reduction isn't either.

Not only does it get 75% evasion but it also gets 75% magic damage reduction.

The fact that techmechs early game are abused means that something isn't balanced properly if their role completely changes once it is late game.

You understood the quote incorrectly. It's not a big deal to give orders manually. Also: "As the Tech Mech is a fragile unit, it will die quickly in battle for the cost of the invested 350 gold."

The quote does not support your argument at all.

Also in the guide there is nothing written about the tech mech "[...] can be killed by only more expensive tanks and remarks that it is only viable early game". You are probably refering to:

b) In the early game you might use the Tech Mech to heal your tank on the field, making it possible to skip time without creeping at the control point. This is only viable in the early game, as higher level tanks (and more expensive tanks) will kill it incredible fast. The repaired hit points will be rather low in comparison to the total hit points in the late game anyway. Even in the early game it is not a wise decision to keep the Tech Mech in the front line. It should always stay in the back, but still close enough to repair soon.

But obviously just this use of on-field repair is only viable in the early game and there is no mentioning of lower level (and/or cost) tanks being unable to kill the mech. It's only the high level/cost tanks which kill the tech mech so much faster that on-field repair is not viable at all.
