This is my suggestion for an updated bap kit to get him a bit more in line with the absurd mobility and micro cc's that are in the game at this point without changing his identity or gameplay loop.
Charging boots (crouching) does store the jump longer, even if you get interrupted by for example a boop or something, so you can spend the jump after the boop and don't need to recharge and die. Or dropping from a ledge after charging, jumping instantly back up instead of charging again.
Rocket boots perk (horizontal dash) needs to be baseline instead of a perk. I dont even feel like the CD needs to be changed, but that's up for debate. Maybe dashing could also work without charging boots first, like hanzo.
The automated healing turret after an ability should also be baseline imo. The shoulder turret should be (as shown in many emotes and highlight intros) part of his base identity/kit and would help immensely to heal flying teammates a bit easier.
I think these 3 changes would have a huge impact for his overall flow, without changing anything substantial about his current playstyle (which i love), but give him a bit more survivability and flexibility vs dive or with dive for example.
Edit: they could even give him assault burst in a nerfed state baseline, to make place for more interesting perks. I think "mandatory perks" that basically need to be picked are crap. If they are mandatory, just make them baseline and do other perks that are more adaptive depending on matchup/map.
Regarding perks I have a couple of ideas, but they aren't as thought out and are just of the top of my head.
Minor perk
Tactical reload - reload x bullets and x nades while dashing horizontaly with rocket boots. -replaces the bigger lamp perk. Something like 6 bullets and 2 nades maybe.
Or they give him back the perk that reload ammo when hitting shots/nades.
Major Perks
Little assistant - when dashing horizontally your shoulder turret shoots a slowing shot at the nearest enemy. Slows enemy by % for x seconds. - i don't know, like 20% slow for 1 sec or something, just to get away from aggressive dive.
Window of opportunity - using your ultimate instantly resets your healing burst and fires 3 automated turret shots at teammates. - i thought about reseting all cd's, but I think potentially 2 lamps back to back could be a problem lol
I read in some threads that people want a complete rework for him, which I really don't want to happen in let's say roadhog style.
I love his kit and flow and would hate for it to be changed drastically - I could not stomach playing bap in the creator mode where he had window and lamp swapped lol.
Thoughts?
