Try to improve counter picking skills
Counterpicking is one of the most overrated tactics in Dota 2.
Many "Counterpicks" Aren't Counterpicks
- Myth: They have
Riki, therefore I should pick 
Bounty Hunter or 
Slardar so we have vision of him. - Reality: A smart player isn't going to auto attack some creeps, then initiate on you so you have time to (a) see him, (b) cast your true sight ult. Reactionary/Premeditated ults like
Amplify Damage and 
Track won't prevent a Riki from initiating onto you, using cloud to silence, and ripping you apart. Only good team play, map awareness, and use of 
Sentry Wards/
Gem will help.
Amplify Damage/Track/
Dust/Etc. can help if you are on the offensive, and ganking a braindead Riki with no map awareness that's farming the lane.
