1. Mr. Crow is busy. Crow is needed by the whole team. Other lanes may need a flask or a clarity or they may have farmed their basic items giving them more advantage in lane fights, and crow needs time to deliver these items. Against professional players, if they see slight advantage over you they are going to plan and execute an attack to destroy you totally. Not having important items like magic stick, urn, bracers, etc, while the opponents on your lane already have means your in a big disadvantage.
2. Waste of Gold. You may say that if the crow is busy, why not buy another crow for mid hero? The reason why I won't do that is because another crow would cost you 400 gold. 2 Crows is not important in mid and late game, where team fights and ganks/gangs are constantly happening. You cannot use bottle crow in clash, it's either you kill them or you die. After winning team fights, it is a good idea to push near towers because of advantage and not to farm and use bottle crow.
3. Lane disadvantage for supports. You may say that supports can buy crow for you since they don't need to farm luxury items. Then, you will have your supports buy 2 chicks 1 observer wards early game. One support wont have any stat or regen items, but, wisely you'll buy regen items instead of stats. So, he will only have around 400hp. Supports won't be advised to last hit creeps a lot, they have to wait for 200 seconds to buy one crow and another 200 seconds to buy another crow. If the supports farm, the carry on the lane will be delayed, thus, making the opponent's carry have advantage over them. After 400 seconds and the supports successfully boght the 2 crows, the opponents who happened to only have one crow, will have their core items and ready to finish you off at your lane in no time.
4. Rune > Refill. Good Players know when to use skills to push a mid lane for the opponent to have a busy life defending the lane while you go for runes. Having runes gives you more advantage at mid. If you have a regen, you can harass him until he make a trip to the fountain. If you have illusions you can bait him with one illusion and gank other lanes or simply use these illusions to have advantage at farming. If you have double damage rune, you can harass him or outfarmed him. Haste can help you kill him or gank other lanes for another team advantage. Instead of refilling, battle for the runes.
5. Farm over you, Leave you or Gank you. There is no need to fear laning with bottle-crow players. There are 3 choices in dealing with these type of players. 1 counter is to farm over him. Farm... Don't harass.. Farm.. He will feel like a jackass having bottle crow but he can't use it because he has full hp. He will resort to spamming skills, which gives you a great advantage. You will be harder to get ganged up because you're tower hugging because of his bad move. 2nd counter to Bottle-Crow is Leave him. Gank other lanes after getting some levels and dominate other lanes. You can get even richer than him after successfully killing other heroes and getting towers. Spending 400 gold from crow is now a mega fail move for that team. 3rd option is to gank him. One reason of chinese players why they don't get ganged up easily at mid is because they love to move a lot. Having bottle crow makes you predictable. Gankers will know that you are somewhere beside your tower. Good gankers will make your bottle-crow strategy cry.
