I had a main account from 2012 and then I created this one because of high bootrate with my other(this is due to me just letting myself get booted and not caring, this being before I played competitively). now I see this as my main and my previous as my alt as I use warlight daily with this account and every second day with the other to make a move in 2v2ladder which is all I use it for. I know some people use alts because if they used their actual accounts then no one would join out of fear and some people use it to troll.
TL;DR:
- due to highbootrate
- due to no one willing to join if their actual account where used
- to troll
These are the only reasons I can think of, sure there are others.
