Not just 300hp, but 100 of it is armor so really he has more
Why does he have so much?
He does lots of damage at range, so shouldn’t he have less HP? Isn’t that why they nerfed Cassidy down from 225hp even though he also has a big hitbox for a DPS?
That said, both Cassidy and Bastion have their “sticky grenade” mechanic. Considering how powerful Cassidy’s version is, Bastion’s just feels lacklustre! Haha
Bastion kind of “needs” his more than Cassidy. The gunslinger tends to be able to get kills without the grenade easily enough.
Thing is he doesn’t really have good dmg at range. In turret form his dmg fall off is quite bad. In his scout form he’s basically just a bigger and slower version of Soldier 76.
Even at his best in tank mode and at close range he tends to do less dmg than Sojourn. Now give Bastion a sliding leap, a charge shot capable of one shotting 200hp enemies and a hitbox half the size and you can lower his HP.
Because he is as big as Rein while having no defensive options. Easily one of the squishiest dps in the game despite the fact he has 300 hp. Very easy to shot at him in his normal form.
Maybe if you consider “just outside Brigitte melee range” as “long range”. Bastion’s SMG has a really harsh falloff penalty, and does practically no damage compared to sentry mode–he’s not sitting in the 20-25m bracket raining down pinpoint shots and doming people for 120 damage a pop, unlike ThicCree.
Also, Zarya and Junkerqueen are smaller than Baston, hope this helps.
