Should I play with mouse or mousepad?

I've been playing League of Legends ever since Super Galaxy Rumble came out. And since then, i didn't had a mouse. I played with my mousepad on my MacBook. I found a mouse in our garage on Sunday and I found that a huge majority of people play with mouse. I find that i play really great without mousepad, maining him is fun too. Many of my irl Plat friends saw how i play and they told me "You deserve to be at least to Silver, play with a mouse and you'll be in Silver or at least in Gold in no time" I tried playing with Mouse today and it didnt seem to work out for me, i did bad. Should i keep practicing with my mouse and see how well i do or just stick with my the mousepad?
