Some names of players and teams do a disservice: a plea for professionalism/change

Hey all. I have been watching a lot of the LCS this week and other challenger streams. I'm relatively new to watching competitive LoL and I'm really enjoying it. However, one thing has really been bugging me: "unprofessional" names. Names like Imaqtpie, Nintendudex, Supahotcrew, or IWillDominate just feel... weird. I know gamer handles have a long history and they range from the ridiculous to the symbolic but in the increasingly popular world of Esports I feel like they need to be phased out/ignored.

I know a lot of Esports fans would like to see their game broadcasted on mainstream television and other media outlets instead of the current niche i.e.Twitch/Azubu/etc (I know there is some exceptions). Names of the nature mentioned above is going to slow (IMO) any progress towards these goals of mainstreamness and reaching new demographics.

I think using the players' last names as their in-tournament handles would be a good idea. I feel that no personal identity would be lost and it would make the competitive scene more approachable by traditional sports fans. More viewers = more money.

I'm sure there would be a lot of backlash but I'm interested to see if there are similar perspectives and strong opposition to this type of change.
