i didnt shift goalposts you're still arguing that forcing someone not to be able to make bad builds is good for the game, i made the point that a base toolkit is just that. basic. where we differ is just opinion, you would like it nearly impossible for someone to be unable to tank if he selects the role of tank, i simply think this is wrong and unhealthy for the game, the people that this is designed around aren't the players who stick around playing for years at a time and simply ruins it for the people who are still left.
the game should encourage you to improve and have something to work towards, if you can just log in, put nearly 0 effort in and still succeed then this is a problem.
Let me ask you this, If you were some 15 year old playing BFA would you be encouraged to spend your time playing the game the same way a 15 year old lost his life back in vanilla/tbc/wotlk? I can't see the answer to this being anything but a resounding NO.
