I'd try it at least for a while. The basics of wrestling can be very valuable. I took wrestling in highschool to improve my Judo and it was way worth it. The body positioning, basic grappling, ground escapes and reversals... I'd at least give it a shot and try to learn something new. Don't be afraid to give up your other classes in order to diversify. Always come back to them and try to apply what you've learned.
