Mindforce chips that increase attributes for a limited time is what they should do.
Agility Increase Chip
I think agility increase chip would be excellent and so easy to implement. Yes we have tp chips but they have a crap design. I would like something that uses so much ME, then increases the running speed of your avatar for a period of time. Would be great for pvp and generally getting around and everyone wizzing about it would look crazy
The better the chip I, II, III etc. the faster you can go
Health Increase Chip
Again much like the agility increase chip, a chip that increases your health by a nice amount for a period of time. They could be used just b4 attacking mobs larger than you could normally take. Again the better the chip, the more health can be added.
Im sure when they find a use for stamina they could include a chip for this as well. Along with the other attributes.
Just my thoughts on Chips
