Why would You need corner icons in Grid/Grid2? The only thing You need to see on grid is:
1) Debuffs
2) Duration of your hots (meaning numeric countdown)
3) Threat
4) Low Mana/Low Health (which is sometimes very annoying - fe Chimaeron)
5) some customizable things..remaining hp or hp missing or name or whatever..

Grid/Grid2 are highly customizable. You can do whatever you want with them to work well for You
