if SE needs to add a tank and a healer every expansion we have an issue :/

im sure more tanks and healers will come , but ppl wanted Sam and Rdm the most , putting Sam on tank wasnt a good idea ....however i think it would be a cool to start implementing jobs with dual roles Sam tank / dps , Rdm caster , healer. It would be unfair for other tank /healers jobs (well Sch excluded since it lvls smn too )
