Legit, half the time I get denied because the orb was somehow visible to my opponent before it was to me.Deny mechanic could be made more reliable and fun, randomly spawning orb that is based on ping and may or may not be visible, exploitable by cheaters ? Yeah, no thanks.
Dota2 deny: hit own low HP creeps, works great, why not have that here ?
If they want to deny, how about pushing when they attempt to finish off low HP adds? You know, something more proactive and fun.
