Lennart "Smittyj" Warkus is the top laner for H2K Gaming.
In November 2015, SmittyJ moved from Europe to North America to join Team Dignitas as part of their line-up for the NA LCS 2016 Spring Season. However, after the first week, Dignitas decided to replace Smittyj with BillyBoss, citing disciplinary issues as the reason for their decision. They also mentioned that he would be moving back to Europe.
After Week 7 of the EU LCS, Smittyj joined Giants Gaming, replacing Atom.
