Right now, i think the only real elite character is Ninja Mono. Here's how the existing ones could be imoproved:
Pointman Elite:
*Can throw blocks to bottom of board by holding space during dropping
* Can use the mass collect Ninja Mono has, but with storage.
Puhser Elite:
* Can push a block two columns to the left or right by holding space during the clicking
* Some kind of slowdown mode, that only works for a few seconds and would take a while to recharge, but would be vital to strategy
I would also suggest these characters
Eraser Elite
* has same erasing ability as Pro
* can erase entire bottom row, much like Ninja Mono's shrukiken, in that it takes a while to charge
DaVinci
* the main purpose of this guy would be to paint blocks different colors, but the catch is that it's a random different color. So if you really didn't want a color, and decided to take a risk, you'd hold down the left mouse button and it'd turn into a random different color, allowing this character to make or break a session.
* He could charge up a move that turns a upcoming block into a rainbow block. This would, of course, take time to charge.
Agree?
