glyphs for tanks ( warriors )

[Theanimal]

Major

Glyph of Revenge - This one is a great choice - and lets you macro Revenge and HS together, guilt-free.

Glyph of Sunder Armor - The choice for AoE tanking, and more.

Glyph of Blocking - This is what will fill in your third glyph spot, at 80. This works out well, since we can't get it now (it requires Inscripting beyond BC levels), and we don't have the slot yet. Replace Sunder Armor with it if it becomes available before you get the third slot.

Minor

Glyph of Charge - This compliments Warbringer, allowing even greater mobility.

Glyph of Thunderclap - A really, really nice effect for a minor glyph. Grabbing large groups of mobs has never been easier.

Glyph of Bloodrage We have a third glyph slot, Bloodrage is a skill we use - its only natural, however insignificant. This is more of a boon to soloing warriors.

Glyph of Thunder Clap and Glyph of Revenge are must have for level 70 warriors looking to level to 80 as prot. I'm in the process myself at the moment.
