Infinity boots, mage's book, master wand. It's just the robes that will be rendered obsolete, the other items will always have a purpose and are major best in slot upgrades.
If barrows came out we'd be ready for KQ, which at that point would be ready to come out. Otherwise it's just a really OP boss that 3 hits you xD
Not to mention we'd actually have some tank gear for literally any other activity.
Also, Contact was an 07 quest. We won't get that, but PP is still a great thing to have. As long as you get a sceptre early it's a good training area. Or moneymaker.
