There are so many complainers asking for a panel to see your allies health/mana, and your enemies items. THIS SHOULD NOT BE IN THE GAME, THIS WILL MAKE IT EASY MODE.
Dota has both and is anything but "easy mode." It doesn't make anything easier when BOTH SIDES have it.
Reason #1: This will eliminate the already small amount of communication between teammates in this game. I've played some games with my team on Vent,
Games should not be designed for people using vent. People *without* vent need this information.
Reason #2: The game already has barely any micro-managing going on. If you're an assassin micro is practically non-existent. If you're a general, there are few times you need to: getting your minions to set off Reg's mines, getting your gunners to attack towers, and harassing someone with spirits. Beyond that there's almost nothing. If you look at pro RTS players, their mouse is constantly moving
This game is not designed for pro RTS players - if anything it's for the opposite. The interface is very streamlined (though flawed in different ways) compared to something like Dota, which is using the actual interface of a RTS.
Reason #3: This will make people lazier when they can just glance at the panel without bothering to type anything to let their teammates know they're at low mana, and eliminate the need of people looking at the item list to come up with their own strategies when they can just copy the items of someone who pwned them.
You learn through observation - that's the most effective type of learning. The current situation is like trying to teach a person to read but constantly moving the book around while they try to read the words.
Reason #4: Compared to others, this game is very easy to master. Knowing is half the battle. Literally. If you have enough experience to know that the scaled helm is better than the plate visor, you're already at a considerable advantage over someone who might not, even if you have equal skill level, micro-skills, memory, reflex etc.. A panel will make it even easier, making it practically a joke.
The truth comes out - you don't want other people to play better, since it's "so easy" for you.
What a joke.
Think of other games. I haven't played Warcraft 3 in a while, but as far as I remember, allied heroes were not shown in the side panel, if you had a Paladin with Holy Light or something, you had to mouse over allies to see their health/mana.
And you could click on them to see their level, health, mana, and items.
