IS like you say LB isnt that necessary, is not like ffxi and the 2hr ability where with out it the fight was slim to nothing to win.

LB is there to smooth the fight not to win it , when you play with friends, fight arent as hard making LB a fun button but in pug LB makes a huge difference since Pug run can be a bit chaotic.

LB changes is more to control ppl discriminate on classes, If you wanna rely on LB you have no choice but to have 1 of each class but if you feel confident that you and your friends dont need it then you can set the group the way you want it

so at the end they arent forcing anything on the player
