Na, everyone always say they are smurfing anyways lol it wont gave you any pick advantage anyways .. me i dont say a single word and every game i muted everyone no exception for the first 10 min, that my ''minding'' time, xD once you've won your lane, your 7/0 and your proove that you should be considered as ''better'' then any other else then you can start trying to guide your team , and youl have 90% more chance that people listen to you
.
Anyways if you start the game saying to everyone that your ''better'' then anyone and you worth more you never know what can happen, if you vs an other smurf? and got wreck finally? you wont feel pretty good :P
(Also .. Just saying, it up to you.. if i where you i might woudnt gave my IP ina public forum post like you do.. use a Gmail adresse only or Imap\Pop3 only if you want to let public a way to join you. im working in internet security and trust me, if i say that it for a good reason)
