With a little work you can program the zboard to do the key strings needed for the combos. That alone makes it worth it to me... especially once you are talking combos that have 5 follow up keys to exicute!
No More! just 1 key and watch the blood splatter fly!
You use the zboard 'engine' program to program the 4-0 keys to do the combos. just put the actual combos in the ALT+# slots, then in the 'engine' program edit the 4-0 slots to call up the right set of keystrokes, ALT+4,ALT+2 for example...
I love the thing even though you have to exit the game and update the key programing when you get a new or higher ranked combo.
I am considering redoing it by sacrificing my 'emote' keys to use them as the auto-combo keys just so I can have 12 set up instead of just 7.
