Yes, I have my Moleman at rank 4 and sig 180 and have no intentions of ranking him down. If you run suicides he is still the best skill champion to rank up (a solid argument can be made for Shang Chi). He still has great damage and the ability to shrug off debuffs, can still counter evade and autoblock, just not in frenzy. He is not as good as he was but if you look at his kit objectively then I still think he is a great champion.
