Yeah, the rocket splash damage isn’t amazing.
It would be 2 shots to destroy Bapt’s generator but unless they are really close to the generator the splash damage of 2 rockets probably wouldn’t amount to much more than 160 damage anyway. So you’d still be somewhat effective, you could destroy the generator in flight time + 1 sec and deal about 160 damage to everyone near it.
I’d still be getting damage out.
This isn’t so bad as those two shots are basically free “guaranteed hits” and my experience with Bastion’s ult is everyone just scatters and goes into “maximum evasion mode” so you’d be lucky to get splash damage of a single rocket on them.
2 rockets leaving 2 (or maybe 3) enemies at only 40HP within about 1.4 sec is pretty good. That’s better than I usually do for my first 2 rockets fired at the enemy.
Biggest concern as always is a DVA’s DM just eating my rockets. For a 5 rocket string she can eat 4 of them. Also Orisa or rein or even Winston shield, even hammond can just body block 4 rockets! Roadhog with breather can absorb 5 rockets. It feeds Zarya’s bubbles way too much. Bastion’s ult is screwed far more by basically any tanks being in the game.
IMO: if you’re up against many tanks, just use your ult to jump to high ground. It’ll probably be a waste trying to use it offensively.
Probably for the best, this ability would be really annoying if it didn’t work that way.
Imagine if a dva bombs was coming in, everyone rushed to hide in an immortality field and they all got wasted anyway.
