Definitely appreciate what you’re on about here, and would like to contribute:
Work critical spots. On advanced, you need to be hitting crits, not just hitting. This is why I’ve been successful with Toby in advanced. I don’t even feel like my Toby game is THAT great, but he packs powerful crits.
Contrariwise, this is why I don’t really like Ambra for Advanced. Her Staff locks on, but it can’t score crits. Guys in advanced just have too much life and hit too hard for her to drain them out successfully.
Reyna I DO like in advanced because she heals in bursts. Overshield and 300+ health, instantly. It’s much more likely to save a friend than Ambra or Miko’s healing-over-time. If you have her Lore Legendary, the Snazzy Timepiece, she can also tick-heal people back to full in between encounters. Plus her Priority Target is REALLY useful for helping your friends in laying out the big boppers of advanced.
Mostly, advanced just forces you into playing roles more intently. In normal, most every Battleborn can handle any kind of bad guy, even in swarms. In advanced, the increase in damage and life means you need to know your role, and stick to it. This can be hard in PUG groups.
It also can get difficult if someone goes freelancing for kills or loot. If somebody runs right into the teeth of the enemy, you may just have to let them use up a life. Too many times you see somebody Leeeeeroy Jenkins their way in, and if you go in for the revive, you’re in a body bag too. So is the guy who goes to revive you. This happens altogether too much on Heliophage advanced, or the Thrall fiesta at the beginning of Sentinel. Somebody goes and triggers ALL the various clusters, and before you know it the party is wiped. Bottom line: stay within arms reach of each other. Not so close that one AoE from a Thrall Brute KO’s 3 of you, but close enough to get revives and NOT trigger new clusters of baddies from swarming on you.
I still just prefer Reyna and Alani as healers on most advanced missions because of the increased offensive potential via scoring critical hits more easily and the fact their healing comes in bursts as opposed to ticks. Miko has very strong tick-healing, and its crit damage is very nice, so I feel it is a good choice too.
