People complain about a unit being underpowered, next update that unit will be useless, don't worry next update aserai tribals will be the worst.
I remember this happening to almost every unit since the beta, Empire Menavs ,legios and palatine Guards, Vlandia volgiers and sergeants, Sturgia warriros and berzerks, Khuzait spear infantry , and other few.
The counter the a full tribal team is pray the enemy is dumb playing it.
