The thing with running multiple characters is that you can decide how much play time you give them but if you can dedicate even 20-30 minutes a day, you will notice that you now have a lot bigger stash of materials. 4-8 Enhancement Cores extra daily, 2-4 additional upgrade mods a week.... Most importantly though, you get a better understanding of all the characters and a clearer opinion of where the game really sits. An example would be like me being a Hunter running my Warlock through Stasis... I 100% now can and will agree with all the Lock mains, the nerf to Stasis melee is horrible and needs readjusted immediately. Long story longer....if you enjoy the game you should play multiple classes, if for nothing else at least a fair understanding of all Classes.
