What the hell would you need another set of taunts for? You only really need like 11 or 12 keys depending on your taunt set up.
Efc High, mid, low = QWE in that order
Inc High, mid, low = ASD in that order
Ffc High, mid, low = ZXC in that order
Base is hot = 1
Clear = 2
Loose/ Free Flag = 3
All of those taunts are the only ones you really need, and you dont even need the Free flag one, cause you can just type, loose mid. Also, every single one of those are in a great position if you use default keys.
Also, with what demonic said. Voice chat is actually a much, much better alternative to an extra set of taunts. You have much more of an advantage with using voice chat than taunts. Not to mention, a mic costs like, what, 2 dollars nowadays? You can return pop bottles you find in a park and get a mic.
But seriously, how many ctf taunts do you have where you would need an extra set of them? Please explain that to me. Hell I even have some non team chat custom ones for joking around. :/
