What do you think should be buffed in particular? I don’t play Sym but i think she might use 250hp (+50 more shields) like another builder, Torb.
From what i see playing against her: she has enough damage but is too easy to kill (same with Junkrat, Pharah, Bastion and somewhat McCree if they’re not pocketed).
Also, her ultimate fits a tank better than a DPS. I disagree with you that teleporter is useless – it is very useful (after infinite duration buff).
But as i said, it’s quite similar to Junk. I want my 0.3 meter direct hitbox grenades back cuz Pharah got her 80 damage splash back without compensation nerfs (but then damage need to be reduced to 120 cuz it’s kinda OP with 130).
But if that happens people will whine and cry endlessly about getting deleted by richochets so the devs will no choice but nerf JR again into oblivion. I’m fine cuz now he’s playable for dedicated mains like me even if he’s barely playable for non-mains (above 3000).
