Note
I've made a post with these ideas before, but it was a big wall of text too tiresome to read, so I've summarized those ideas and made a better formatted version of them.
Introduction
Going directly to the answer: what I think should be done about Buck is to give him more sustain and a shorter cooldown on his Net Shot, as he's extremely dependent on it. It would also be great if we could have a better supreme, it should feel like something special, something that only a powerful skill could do, and that actually helps the team, and not just some stat buff.
Buck seems to be the most unique champion in-game: he's bulky, with sustain skills and high mobility, while being able to liquify enemies using his combo or just fighting for a prolonged time, a position no other champion holds, but as of now, he lacks this sustain, as his health isn't comparable to other bulky characters, and his regeneration skill is too weak, allowing any high damage to nullify it. Also, his combo is hard to handle as it has a high cooldown, so he ends up being weaker most of the time.
Currently Buck can lose a 1v1 against Pip quite easily or be burst down by Cassie in 3 seconds, even with his 3000 health.
My suggestions would go like this:
- Buff his regeneration skill.
Regeneration
Gives Buck 30% damage resistance and heals for 1000 health through 4 seconds.
10 seconds cooldown
With this 30% damage recution Buck wouldn't suffer as much from high bursts.
- Give his reload a passive to compensate the time it takes.
(This could also be adressed by giving Buck a reload the same speed as other characters, or by giving him a higher ammo cap, while he reloads more bullets at a time.)
Passive
For every bullet that Buck reloads, after the first one, reduces the cooldown of Net Shot by 10%.
Now Buck has a way to shorten his Net Shot cooldown, being able to do his combo more often while not being as hardly punished if he misses it.
- Remake his supreme.
Great Net
Buck throws a ball that opens up into a giant net grabbing any target in its AOE and pushing them to the center. Deals damage, applies slow and gives bonus damage to Buck and his allies.
A special animation for a special skill, with a mechanic that's unique and helps the team, it can also make some great team combos.
Conclusion
With changes like these Buck would feel more rewarding without the need to mess with his weapon's damage, he would maintain his spot as a sustained damage dealer able to flank, while still depending on his skills for such.
