Let me be very, very clear about the next expansion

Or scale item levels in instanced pvp?
Just hit level 60?
Your ilvl 100 quest weapon will scale up to ilvl 259 - the current highest honor rank upgrade.
ilvl 100 weapons has
100 stam
100 main stat agi/str or int
40 haste
20 crit

scale it to 259
and now it’s
259 stam
259 main stat
103 haste
51 crit

say if you wanted to customise your gear for more haste and vers and you find an ilvl 95 weapon
95 stam
95 main stat
25 haste
25 vers

scale that up to ilvl 259
now you have
259 stam
259 maint stat
77 haste
77 vers

this gives flexibility for whatever gear you have that you can bring to instanced pvp.

I welcome you to review my suggestion and provide feedback or criticism.
