i have beaten the nf and the heroic but the nf and the weekly(depending on modifiers) just isn't fun the a.i has better shields better guns that never have to reload and splash damage mixed with there being more of them than us..its never really fair or fun regardless if you have the guns to take down shields .....to put in short being level 29 and being meleed by a lvl 28 dreg is neither fair nor fun and does nothing but insult your player base
