Helcurt is definitely not a braindead hero. Sometimes you have to wait the right moment to go initiate a war/kidnapping opponent's core. You can't just jump into their core when there's still many CC that are ready to lock you out.
Helcurt is not easy, I mastered him after 20 matches I knew how to farm, gank and split push efficiently. You don't just max 2nd skill and hope you get decent damage, you need to assert dominance early game even at lvl 1 you can kill an enemy mage or marksman. Cheers, Happy Gaming!
"Top 5 heroes I really don't like fighting against because they're annoying so in my mind I'll consider them braindead heroes who doesn't require any skill to play unlike me who is using a complex hero that actually requires skill and proper timing"
