Okay so I'm gonna push back a little here because Oblivion Acrobatics is actually not a trap, but it's also not what you think it is coming from Skyrim.
The thing is, Acrobatics doesn't make you jump higher or farther in the way that matters for traversal. What it actually does is reduce fall damage, and that's genuinely useful if you're exploring Oblivion's dungeons and Daedric ruins where you're constantly dropping down shafts or getting knocked off ledges. High Acrobatics means you can just... yeet yourself off things without dying. On higher difficulties that's real value.
Where it gets weird is that it also levels when you jump, so a lot of people think "oh I should jump everywhere" and end up wasting stamina for no reason. You don't need to actively train it—it levels naturally if you're just playing. The skill itself is more defensive than offensive, which is why it feels invisible compared to Blade or Athletics.
That said, if you're not playing on a high difficulty and you're not planning to do a lot of vertical dungeon crawling, it's not essential. You can probably get away with dropping it in favor of something more directly useful. But it's not bad - it's just less flashy than Skyrim's perks make you expect. Oblivion's skill system is way more passive and stat-focused overall, so nothing feels as impactful.
What difficulty are you playing on?
