That's the beauty of this game, sub jobs are extremely flexible and it's up to us to use them to suit our play style. Certain subs are defacto for certain situations due to many years of testing, there is no questions about those certain subs and moot point trying to be "different". If you wanna tank, keep hate and deal good damage, warrior is one of those defacto sub jobs bar none, stop arguing. Otherwise there are many other sub jobs you can try and experiment for solo play or small groups set up where you don't have to be the main tank, or where you don't have dedicated healer or just want to play it outside the box. This game is extremely flexible and we should be able to play it how we want, as long as we are aware certain situation require you do certain things, and stop trying to argue since those methods have been tried and tested for us. Then again, teamwork and understanding of game mechanics is also something that will help to break the norm and let you play outside the box - hence you should have a few in game friends so you can experiments with different sub jobs.
