I see the point of people against it, but I believe in many cases it gives more than it takes. Anyway I don't think it matters much, it just makes the map a little less bland with the shops placed where they are. Imo mana doesn't carry lots of information up to the point where constantly checking enemy mana can be used to deceive you. You have to click enemy heroes to check item progression anyway and you want to check if he has bkb/hex/radience/manta or other big items that change the powerlevel of a hero a lot. What I don't understand is no manabars for allies. This is just dumb up to the point where it doesn't matter for high level clan play (teamspeak helps a lot here) but makes play more difficult for lower levels. You don't want to rightclick-move for pickup so that you can manage the crow entirely via hotkeys to not leave the lane with your screen. (maybe waterd might like it as soon as he gets used to it, I think his main argument against currier system was that you have to interrupt lasthitting for shopping) Also you don't want to auto-drop on leaving the base because in higher lvl of play you carry items for different heroes that play on the same lane simultaneously. For pubbing you only need two keys, deliver and move faster.
