Libra isn't all that powerful here are her counters(though some counters here don't apply when with Libra + Clone Army) for all factions. Some counters here don't kill Libra + Clones directly but they can be used to weaken her and/or clone army.
All: Attack Dogs
Allied: massed Robot Tanks, massed Rocketeers, Warhawks, Target Painter+Mercury Strike, Mercury IFV, all T3 seige vehicles, Siegfried, Thors, Blizzard Tanks
Soviet: massed Terror Drones, Borillos(with TDs inside), all T3 anti-infantry air units, Morales, Buratinos, Nuwa Cannons(if caught in blast of attack), Chitzkoi
Epsilon: Risen Railgun, massed Stingers, massed Gattling Tanks, Basilisks, Magnetron(Immobilizer), Shadow Tanks(when ambushing), Stalkers(Immobilizer), Irkalla(area denial), Geneburst, Plague Splatters(best against large groups of clone), Molebomb, Malver (Mind Suppression/area denial)
Miners are hard to tip over while they are moving since they are heavy units. I agree though it's better to replace dead Libra than dead Miners.
Essentially her counters are entire armies of units and that's not including when she has clones or realistically a backup of units from the rest of PsiCorps, lol. Trying to amass some of the counters you mentioned would leave you wide open to a counter-attack of many other units that PsiCorps possesses.
Two T1 anti-infantry defenses placed correctly close to each other can kill Tanya, same with 2 T2 defenses and 1 T1 defence + 1 T2. defense. Walls can also be used to block C4 attack on vital buildings. Tanya's overall buff only affects her attack(ROF and heavy infantry bonus) and range(by +.5) which only improves her against high tier infantry like Desolators and slighty better hit and run but Tanya will still have her weak hit point stats and her vulnerability of not attacking when she is planting C4. How does that make her a 'one man army'?
You're suggesting that the subject player essentially wall their base in turrets and have a force of T3 anti-Infantry units to deal with her, though in plenty of maps a player is not likely to have the resources or time to do such a thing.
I don't know if I agree with you or not though, she already massacres groups of T1 and in some cases T2 Infantry, and is pretty effective against lightly armored units as well. That's why I call her a one man army, when she can essentially solo a sizable group of units alone. In many instances I've seen her wipe out a force of my units with her additional range and firepower with her rate of fire, her rate of fire is already intense and she has decent range on top of that. Giving her a boost in range and ROF for the purpose of being able to kill heavy Infantry more easily will also allow her to slaughter even more units below their level.
I think a better buff would be just to give her a heavy Infantry bonus and give her more armor that is more durable against the weaponry that desolators use and other units alike which easily threaten her, and MAYBE a range boost.
EDIT: Another thing I would like to ask is if it's possible to add some sort of notification sound when a waypoint is completed.
2nd edit: Should just give Tanya power armor. lol
