Short answer; no.

Long answer: If you’re really struggling and still quite early, swapping to Samurai isn’t a terrible idea, it has a good stat spread and good starting gear. Elden Ring though, like all Soulsborne games, doesn’t really put much empthasis on your class. All it is is your starting stats and gear. A couple bosses in, your starting stats won’t matter near as much as how you’ve been leveling, and you can find the gear Samurai starts with in the starting area, if you really want to use a katana. So feel free to do whatever you want/is fun for you, but I wouldn’t bother, personally.

Just to add what others are saying, class doesn’t matter. I’d say leveling your weapons is far more important.

This game can be beaten fully naked at lvl 1. Your starting character has very little effect on the rest of your playthrough.

The game doesn’t have classes in the same way other RPGs do, so you’re free to use any and all items you have the minimum stat requirements for. Any time you level up, you can increase any stat as many times as your runes will let you.

If I have one piece of advice, it’s to increase your Vigor to about 60 by the time you beat the game. You can put enough points into other stats to have medium weight and use the weapons and spells you want, and for the most part, the rest can go into Vigor. This is especially good in the beginning when you’re still learning the game.

I recently restarted to a different class and am glad I did. However, if you’re having fun with your current early game build no reason to change it.

It literally doesn’t matter at all in the slightest. First time souls-borne and you’re already just looking stuff up? Eww.
