Yes tamer is over powered, what are you on? Now how much time and effort it takes to get full steel? Mean while you AFK level a pet.
Getting steel or better is not a skill so I dont know why you are equating skill to gear. All you are doing is pressing one button. The other player has to read the unreadable animations of a terror bird which are out of sync, hope the server isnt lagging because the attack are so quick that they will skip frames over the lag, while being able to charge up a swing to hit the bird that has 4 times as much health as the player before dying.
Terror bird mounted is the most broken thing in the game and pretty much encounterable. Cant even run away from them on horse, cant kill the rider because they are mounted.
Mounted tamer is not supposed to even be a build in the game, we are missing several skills like beast mastering that would be another 100 points to use those busted as can be pets.
If you are saying its not overpowered mean you are in some sort of echo chamber because these pets are the most busted things in the game from long before release.
