-Lag: With Rosalina and Sonic or other similarly precise characters, mainly. With characters like that, any amount of input lag completely throws me off. I can't even do Lunar Landing that well online. It can also make it difficult to deal with otherwise simple to avoid things. I once had a match with terrible input lag against a Little Mac. They beat me by doing nothing but Side Smashes. I simply couldn't react properly because the input lag was that bad. And I NEARLY beat him too.
-Tired: I am rarely in tip top shape because of college and general sleep issues. People generally notice without me saying so.
-Sick: I have had quite a few health issues lately. Again, people generally notice without me saying so.
-Out of Practice: Most of my Smash time lately had been single-player stuff on Wii U (mainly All-Star on Hard with everyone), or practicing with lesser used characters on 3DS. This generally leaves me playing poorly on the first few matches with friends, even with my mains, especially since modes like All-Star require a different mindset to a normal 1v1, and the mode could legitimately have it's own tier list. Also, my inability to even play the Wii U version that often doesn't help either. This should all start becoming less of an issue soon, though.
-C-Stick Problems: I think this only happens online, but sometimes when I try to use my C-Stick for a Smash attack or an aerial that isn't N-air, my character will just jab or N-air. My C-Stick IS set to Smash, but sometimes this happens. Again, I think it's an online issue only, but since that's where most of my time against human players is, it's frustrating.
