Depends on what your prefer to play... if you do straight firefight with boosts, yes that's the best way to earn xp quickly, but you'll burn out quickly. Take this with a grain of salt as I haven't checked your service record... but also look at your arena lists (I like big team super fiesta personally). Not only is the xp decent, but it also helps with commendations, which also gives xp when you finish the different tiers and also finish them completely. Yes, heroic firefight is going to be the best option, especially with a boost on. But I burned out fairly quickly and it does get monotonous after a while, so feel free to mix it up... try some different game modes, always use a boost.
What is the best way to reach lvl 152?
