This does nothing to offset that biotic grenade heals your entire team and prevent the entire enemy team from healing. I’m a bronze with patato aim and I can still get huge value from her kit. I’d rather be playing mercy - I hate any sniper - but when it comes down to it her kit is over bloated and on relatively short cooldowns.
I would take bio nade over res any day of the week.
I use her to sleep the bastion, prevent the road hog, mercy, moira from healing. All four staple picks in most bronze games. Her damage is more than mercy too so I can gun down an sleep most tanks, also good for sleeping that hammond that keeps rolling around and around on point denying access. Basically she’s almost essential, at the very least your job is going to be a lot harder without her.
When ow2 comes out she will have mercy’s passive heal and only 1 shielding tank (her biggest weakness) to contend with. She’s a sleeping nightmare waiting to happen, unless the widows run rampaant.
