ascent is the only good map in the pool
breeze, icebox, haven, extremely gimmicky maps that require agents like viper and tons and tons of post plants
bind and split are just pure garbo
There is many problems with Valorant at the moment, abilities aren't really fun to watch, they're like the least fun aspect of the game because you always use them in the same way. People think there are more agents so there would be more interesting way to play the game, nope.
One thing you can do to check is hop on Asuna's stream, watch how pros play Icebox, it's literally the exact same way to play every single round, it's not remotely fun to watch or has any depth to it.
That's the real issue, despite having so many agents and so many abilities, you can't balance them all to be "good" at the same level, there's always MUST HAVE agents at the pro level (viper, sova/skye, jett) that basically locks in your play style. It's not like CS where each person has the same utility which makes tactics actually much more dynamic than in Val.
So, Riot needs to completely revamp their game to change this, minor balance patches will not do anything, but I don't see them doing it because they've never had a good track record of making ground breaking changes like these. (They're satisfied with bringing a lot of casual fanbase, but their games have depths of puddles)
