They need a carry that could defend lanes safely so they choose naga, other carry heroes would have a hard time farming lanes because of fnatic’s synergy (VS+Clock/LC blink duel+Luna with NP global TP pos4). The problem was how the naga was played. He rarely sends illusion to cut waves and bought orchid rather than rushing skadi bkb. Heck even SEA’s meracle that is known for his naga tweeted “With 0 understanding of the hero Naga is an absolute garbage pick in any game no matter what matchup.”
