Maneuvering and physically blocking movement of enemies becomes much more important than it is in current games if the group needs to protect a wounded member who can't just be healed by the specialized healer standing in the back
Surely this physically blocking movement trick would make sense and enhance tactical depth but there is one important factor the author forgot - lag. When I played WOW I typically had lag of 300ms and many other players had worse. It is extremely important to tell the player where his character will be located when all movement commands reach the server, if his movement can be blocked by things not computable on client side only this convenience is gone.
I doubt about the value of what students could learn (and write in their notes) from such idiot teacher.
I live in Israel I know how websites are created here. Once I inherited code for eShop that was destined to be given to the customer soon. Server part had glaring SQL injection vulnerabilities, the HTML/CSS part did not look the same or even correct in not a single browser. But the worst part was the boss who thinks it is OK to ship this to the customer without fixing and charge money for it. I hope our webmasters will learn from what happens now.
I'm not an expert, I compiled Linux kernel only once and not on embedded system. Also I'm good at generalizing.
Why do people switch to Windows Vista? Windows XP does not support some of the newest hardware. That's it, new OS runs better on new hardware. Why do people use 2.6 kernel on desktops? Old kernels do not support old hardware.
I know, computational power of embedded devices must be as small as possible to reduce energy consumption, cost, weight, whatever. I know, embedded hardware does not evolve the same way as desktop. But there is something in common. When new hardware comes out driver writers support newest OS first and old ones enter "if time permits" mode. Imagine that next year you device must support USB3 (while everything else remains the same). USB3 driver for new kernel is likely to be developed soon, usb3 driver for 2.4 may take longer. (Disclaimer: I know nothing about usb3, it is just an example).
Conclusion: Moore's Law is your friend.
A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it.
