I for the longest of times used dotas arcane hot key system and felt my game play suffered because of it. Sometimes in the heat of the battle it is very possible to miscue certain abilities because of their odd positioning. I propose that dota altogether get rid of hot key placement all over the board and come up with a simple setup. I've been using the HoN setup of placing skills 1-4 in the slots of QWER. Q activates first skill, W second and so on. It took a fair amount of getting used to as I had to relearn all my keys and after countless times pressing F for fissure and realizing it was Q (>_<), I believe I've become a better player because of this. While this setup may not be comfortable to all, it is convenient and close to the A key on which my hand is almost at all times. It would also be great if the inventory could also be hot keyed to say the 1-6 slots (of course people who use heroes like Meepo/Chen would be frustrated, so this part is not set in stone). So I propose a) a restructuring of the keys to the QWER setup so that I don't have to personally set them up but that they are there in position upon downloading the map (if possible) and b) to reset the inventory to be accesable via 1-6 keys (this can be worked out as I'm kinda on the edge about this one personally).
