That's why you gotta practice to make it more comfortable.

I strongly disagree.

Exactly. I have to travel 1900 pixels with my mouse sometimes just to use a potion.
Don't forget I also have to slow down at the end so I won't miss the potion's square.
And don't forget that mostly, I have 2/2 (human..) hands on the keyboard while in a war.

Depending on mouse movements in order to live isn't recommended unless you have 3 hands or more.

Thise might not be what you are looking for Zippo, but you can move your bag of mana potions anywhere you like, even up to the hotkey bar.
I personally use a setup with two bags of potions, one closer to the loot bags for hunting comfort and a minimized one just below the hotkey bar for when I need to run, heal and drink at the same time.

Tip: put f12 most important hotkey (heal), and then to f1 most less important one. That way you can use arrow keys and most important ones hotkeys in 1 hand
and u can safe the another hand for mouse. That helps me a lot, because I'm probably one of the slowest mouse users from whole tipitaka.

why do you say "you have to be a better player" or "u need to practice", if you are playing on a laptop it is very dificult when you have to press the pot icon to heal, the game is good and funny but, it doesen't matters that in tibia you can use pots on hotkeys, it makes the game easier and brings it's funnier, if you are level 40 and you are in a laptop without mouse a player lvl 10 can kill you and more if you have sweaty hands like me.
The game needs to be able to put pots on hk. I know what i am saying :l

You also need to get a mouse. This game is quite difficult to play with out one. The amount of click dragging that has to be done with out one would create waay too much work for yourself. I play on a laptop and I do just fine because i've taken the time to learn the style of play of the game, which you have to do with every new game you play, and gotten used to how hotkeys and potions work. I have a 19" screen for my lap top which is probably more pixels to move my cursor through then your laptop screen. Just move you potion bag closer to your skill bar to shorten the distance.

I don't disagree with your idea but I don't think slapping them on hotkeys would better the situation.

NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

agree with both of them GMs listen to good players not some noobs thats all

The human being developed two hands for a reason.
now we know why
