1. People who don’t look at the warded map
Wards are very important because they light up the map. With proper placement, you can see the enemy’s movements, which can help set up your own gank or avoid enemy gank. I’m sure you’ve heard players complaining about how their supports don’t ward. However, I would also like to point out that that warding will only work if you look at the mini map. So if I warded near the rune area near the river, I expect you to see an enemy walking from the river, into the jungle, and most probably towards your lane to kill you. Warding costs gold. Looking at the map costs you nothing, so in case you aren't looking then why are you not looking!?
2. People who run out of healing range
One of the duties of the support is to keep the core heroes alive and safe. For example, if you’re injured while lane with an Enchantress or a Witch Doctor and they cast Nature’s Attendance or VooDoo Restoration, that means they’re healing you. Unless you have a good reason, you should NOT leave the healing radius. You can only imagine how frustrating it is when you’re trying to heal a hero and he runs away from you.
3. People who don’t understand creep pulling (and has guts to flame)
Supports usually get their farm from assists or jungle. Creep pulling not only helps the support to get farm, but it also keeps the lane from being pushed so far and denies gold and experience from the enemy. Since the enemy creeps are much closer to your own tower, it makes it safer for the carry to farm.
Now I speak from experience when I say that some carriers do not know what pulling is and I get flamed because they ‘don’t have creeps in their lane’ (Exact words: “WTF are you doing taking my creeps, Vengeful!?”). And instead of safely farming behind our tower, they then proceed to leave the lane, enter the jungle, kill the neutral creeps being attacked by our creeps. This, in turn, denies me the mediocre gold and experience I can get outside lane while letting the enemy creeps hit the tower and die ‘unfarmed’ from tower aggro. Can you not!?
4. People who are oblivious of what casting delay means
Playing a Lina or a Leshrac support can be tricky if you’re the only one with the stun. Why? Because their stuns have casting animations and delays that are rather easy to avoid. Aside from casting the skill on the ground in advance, timing and positioning are very important. So if you’re a carry laning with these kinds of heroes, don’t flame the player if the casting wasn’t instant. It’s not their fault if you don’t know that attempting to stun a hasted enemy in broad daylight is most probably a bad idea.
