Increase the item level gap between tomestone gear and savage raid gear.

Tomestone gear is a paricipation reward, there is no reason for it to be that strong. Reduce it to ilvl 610 and the upgraded gear to 620. Then casual players can mix their gear with normal mode raid gear and in the next patch with 24 man raid gear.

Increase the item level of savage raid gear to 640. This means raid gear will be more powerful and a better reward, but mostly you can grind out the gear from the current tier to then use it for progressing in the next tier. Savage raid gear of the current tier will be as strong as the tomestone / normal raid / crafted gear of the next tier. Well, crafted gear will still be a little better thanks to more materia slots.

This leaves room for grind heavy ilvl 630 relic gear and gear from criterion dungeons, which will be the new time sink content for midcore players.
