If you choose to not install Ignite, it's not a waste of space on your computer, because you don't have it... o.o
Some Installers just do not give you that choice.
Also, Akamai and other things that mess up system settings as well as degrade performace are not a nice thing to have on the computer.
Instead of telling the player how to remove this unwanted stuff and how to deactivate unwanted options it would be a lot more polite to give the option of what i would accept on install.
It is unwanted, ignite TOS are creepy, it has no benefits at all for some games and at least akamai was doing quite a lot of bad things to my network performance.
Benefits of ignite ? Not many that actually work for Last Chaos.
So from a simple win/loss point of view ignite is not only not necessary but simply something like adware/malware.
