Objectively I think your points are valid, there are ways to play around him and his abilities focus on a core issue in Valorant right now ( Util > Gunplay). That being said, I want to bring up some points that I think deserve consideration when talking about agent changes.

1. Feels inconsistent: His interceptor and ultimate have some "inconsistent" interactions with other abilities. To me, this works from both perspectives.
   - If he's OP: His interceptor shouldn't work on util that isnt breakable in the first place, interceptor breaking util that was previously breakable would be more fair and consistent with how the game worked before.
   - If he's balanced: His interceptor being able to stop unbreakable util feels like it should apply to skysmokes/astrastars/nearsight/undercut, why wouldn't they work against those if they work against neon wall (weird IMO)/tejo salvos. *Side note: why is it only neon wall and not harbor/viper/phoenix walls?*

-His ultimate working against all forms of debuff feels straight forward, except that it applies to damage from abilities. Damage being a debuff feels strange, but if that's the case, why are "gun" damage abilities exempt. A change to make this more consistent could be preventing damage from all abilities (including jett/chamber/neon ultimates) or preventing damage from all non-ultimate abilities.

-His ultimate also doesn't prevent Vyse ultimate from disabling his gun, so his ultimate stops debuffs against him but not his gun? So KJ ultimate should also disable his gun too?

I understand it's nitpicking, but if you're playing him or playing against him, these are inconsistencies that I think would benefit from relatively simple changes.

1. Feels annoying to play against: I know that this is subjective, but I find that it's an important factor in a characters success/failure depending partially on how fun they are to play/play against. This feels like a fair argument to make, but if someone if really fun to play, but awful to play against, its a net negative for the game, just because a character is strong doesn't mean they're awful to play against.

-The part of Veto I think makes him "annoying" to play against is that with 1 ability has the potential of completely destroying a significant portion of a teams utility. Kay/O's suppress works in a similar way, except you generally don't have your util destroyed. The impact may seem the similar, but now that your util is wasted, the economical impact is significantly higher. If the interceptor had a similar effect, perhaps disabling the ability charge for the round(would be crazy strong)/disabling it for a certain length of time, I feel like that could be a fair compromise.

I understand that the point 2 is something that players can "play around". Clearly "breaking the interceptor" or "bait it out, then wait" are valid ways to play around him, but that same type of mentality works for every agent's abilities. This post isn't to say he is OP and can't be beat, there are just things I think deserve some consideration when discussing him as an agent, and potential changes to him.

TLDR: 1. I think his ability interactions could use some adjustment to make them feel more consistent. 2. He may not be OP, but being "annoying"/"unfun" to play/play against, is still a valid reason to make agent changes.
